If you drive a 2026 Toyota 4Runner SR5 and want more all-terrain capability, tire fitment needs to come before tread design or brand name. The factory SR5 uses 245/70R17 tires, while 265/70R17 is a larger 17-inch size some owners consider when they want a fuller stance and more ground clearance without moving to an 18- or 20-inch wheel.
This guide has been narrowed to two 265/70R17 all-terrain options from the original roundup that better match that specific SR5 upsize. These are not universal replacements for every 2026 4Runner trim, so always confirm your door-jamb placard, wheel width, clearance, load index and speed rating before ordering.

Quick Fitment Check for the 2026 4Runner
Before you buy:
- SR5: commonly equipped with 245/70R17 from the factory.
- TRD Off-Road, TRD Pro and Trailhunter: commonly use 18-inch tire packages rather than the 17-inch products reviewed below.
- Limited, Platinum and TRD Sport: commonly use 20-inch tire packages.
- The two products below are specifically 265/70R17, so they should be treated as an SR5 17-inch upsize rather than a universal 2026 4Runner tire.
- Confirm acceptable load index, speed rating, wheel width and body/suspension clearance with your vehicle placard and tire installer before purchase.

Selection Criteria
For this revised roundup, compatibility comes first. Both remaining products are 265/70R17 tires with a T speed rating, making them more relevant to an SR5 owner considering this specific 17-inch upsize than the mismatched 15-inch, 16-inch and other 17-inch sizes removed from the original article.
After fitment, we compared tread design, wet and loose-surface traction, winter capability, tread depth, load index, ride comfort, warranty information and the type of driving each tire suits best. We also considered how much highway refinement you may give up in exchange for stronger off-pavement traction.
Sailun Terramax R/T
A 265/70R17 rugged-terrain tire that combines a deep tread pattern, 115T service rating and Three Peak Mountain Snowflake certification for drivers who need stronger snow and loose-surface traction.
Check Price on AmazonThe Terramax R/T makes the strongest case if your SR5 regularly sees snow, gravel, muddy access roads or mixed on-road/off-road driving. Its 265/70R17 version uses a deep tread and aggressive shoulder design while retaining a 115T service rating.
The biggest advantage is winter versatility. The Terramax R/T carries the Three Peak Mountain Snowflake marking, so it has passed the industry traction test required for severe-snow service. That does not make it equivalent to a dedicated winter tire on ice, but it gives you a more meaningful winter credential than a generic M+S claim.
Why You’ll Like It
- 265/70R17 size suits the specific SR5 upsize covered in this article
- 115T service rating
- Three Peak Mountain Snowflake severe-snow certification
- Deep tread and open shoulder design for loose surfaces
- Designed for mixed pavement and off-road use
- Current Sailun U.S. warranty information lists 50,000-mile/60-month limited tread-life protection, subject to warranty terms
Who Should Buy This
Choose the Terramax R/T if your 4Runner spends meaningful time on gravel, forest roads, snow-covered routes or muddy trails and you still need a tire that can handle normal highway driving.
Who Should Avoid This
Skip it if your priorities are maximum fuel economy, the quietest possible highway ride or factory-size replacement without changing from the SR5’s original 245/70R17 specification. Drivers who spend nearly all their time on pavement may be happier with a less aggressive all-terrain or highway-terrain design.
Buyer Feedback Snapshot
The source article included the sentiment graphic below, but the underlying review sample and methodology were not available for independent verification. Treat it as an informal snapshot rather than a measured product score.
Durability
The Terramax R/T uses a deep tread and rugged shoulder design intended for truck and SUV duty. Its current limited tread-life coverage also gives buyers a clearer manufacturer-backed longevity reference than the older warranty figure used in the original article.
Main Limitation
An aggressive R/T tread can produce more road noise and rolling resistance than a road-focused tire. Also remember that 265/70R17 is an upsize for the 2026 SR5 rather than its factory tire size, so clearance and installation suitability still need to be confirmed.
Finalist Terreno 265/70R17
A 265/70R17 115T all-terrain tire with 12.6/32-inch listed tread depth and an asymmetrical design aimed at balancing everyday road manners with dirt and gravel traction.
Check Price on AmazonThe Terreno is the more road-biased choice of the two remaining tires. Its 265/70R17 size, 115 load index and T speed rating make it relevant to this SR5-upsize comparison, while its tread pattern is aimed at drivers who want additional dirt and gravel grip without moving to an especially aggressive rugged-terrain design.
That makes it easier to justify for commuting, family trips and occasional trail use. The listed 12.6/32-inch tread depth is substantial enough for mixed-surface use, while the asymmetrical tread layout is intended to balance traction and everyday road behavior.
Why You’ll Like It
- 265/70R17 size matches the specific upsize covered in this guide
- 115T service rating
- 12.6/32-inch listed tread depth
- Asymmetrical all-terrain tread design
- Better suited to pavement-heavy use than a more aggressive R/T pattern
- The referenced listing advertises road-hazard coverage; verify current coverage terms before purchase
Who Should Buy This
Consider the Terreno if most of your miles are on pavement but you still want added traction for gravel roads, campsites, dirt tracks and occasional light trail use.
Who Should Avoid This
Choose something more specialized if you regularly drive deep mud, demanding rock trails or severe winter routes. Unlike the Sailun above, the information reviewed for this specific Finalist listing did not establish a Three Peak Mountain Snowflake severe-snow certification.
Buyer Feedback Snapshot
The source article included the sentiment graphic below, but the underlying review sample and methodology were not available for independent verification. Use it only as an informal reference.
Durability
The 12.6/32-inch listed tread depth and all-terrain construction give the Terreno useful tread material for mixed driving. Long-term life will still depend heavily on pressure, alignment, rotation intervals, vehicle load and how much time you spend on abrasive off-road surfaces.
Main Limitation
This is not the strongest choice if verified severe-snow capability or highly aggressive off-road traction is your top priority. It also remains a 265/70R17 upsize rather than the factory 245/70R17 SR5 specification.
How to Choose Between These Two Tires
Choose the Sailun Terramax R/T if: winter traction, snow certification, deeper tread and stronger loose-surface capability matter more than having the mildest possible road manners.
Choose the Finalist Terreno if: most of your driving is on pavement and you want a more value-focused all-terrain option for occasional gravel, dirt and light trails.
Before You Buy a 265/70R17 Tire for a 2026 4Runner SR5
- Read the door-jamb placard first. It is the starting point for factory tire size, load requirements and recommended cold pressure.
- Do not assume every 2026 4Runner uses 17-inch wheels. Many trims use 18- or 20-inch wheels and need completely different tire sizes.
- Understand that 265/70R17 is an upsize. It is larger than the SR5’s common factory 245/70R17 tire.
- Check wheel width and clearance. Tire width and diameter changes can affect suspension clearance, fender clearance and spare-tire storage.
- Match an appropriate load index and speed rating. Do not select a tire solely because the rim diameter and width look correct.
- Expect some driving changes. A larger or heavier all-terrain tire can affect steering feel, acceleration, braking feel, fuel economy and speedometer accuracy.
- Have the final setup approved by a qualified tire installer. Vehicle modifications, aftermarket wheels and load requirements can change what is suitable.
FAQ
What Tire Size Comes on a 2026 Toyota 4Runner SR5?
The 2026 4Runner SR5 commonly uses 245/70R17 tires from the factory. The 265/70R17 products in this article are therefore an upsize rather than a like-for-like factory replacement.
Will 265/70R17 Tires Fit a 2026 4Runner SR5?
Some sixth-generation 4Runner SR5 owners use 265/70R17 tires on 17-inch setups, but that does not make the size an official universal fit. Confirm your wheel width, suspension and body clearance, service rating and installer approval before buying.
Can I Use These Tires on a TRD Off-Road, TRD Pro or Trailhunter?
Not on the common factory 18-inch wheels. The specific Amazon products reviewed here are 17-inch tires. If your 4Runner has 18-inch wheels, shop the exact tire size shown on your door placard instead.
Can I Use These Tires on a Limited, Platinum or TRD Sport?
Not on the common factory 20-inch wheels. These products require a compatible 17-inch wheel setup, so they are not direct replacements for the usual 20-inch tire packages on those trims.
Is the Sailun Terramax R/T Better for Snow?
It has the clearer winter advantage of these two because the Terramax R/T carries the Three Peak Mountain Snowflake severe-snow marking. That certification is more meaningful for winter traction than relying only on an all-season or M+S description.
Are All-Terrain Tires as Quiet as Highway Tires?
Usually not. Larger tread blocks, wider voids and more aggressive shoulders can create additional road noise and rolling resistance. If your 4Runner spends nearly all its time on pavement, prioritize a milder all-terrain pattern rather than choosing the most aggressive tread available.
What Maintenance Helps All-Terrain Tires Last Longer?
Use the vehicle manufacturer’s recommended cold tire pressure unless a qualified tire professional specifies otherwise for your approved setup. Rotate the tires on schedule, correct alignment problems quickly, keep them balanced and inspect the tread and sidewalls after off-road trips. Proper pressure and rotation are especially important when running heavier all-terrain tires.
Wrapping Up
For a 2026 Toyota 4Runner SR5 owner specifically considering a 265/70R17 all-terrain upsize, the Sailun Terramax R/T is the stronger choice when snow certification and rugged-terrain capability matter most. Its deep tread, 115T service rating and Three Peak Mountain Snowflake certification make its purpose clear.
The Finalist Terreno 265/70R17 is the more road-oriented value choice. It makes more sense if you mainly commute and take road trips but still want extra grip for gravel, dirt roads and occasional light trail use.
Neither tire should be purchased solely because it says 265/70R17. Confirm your exact 2026 4Runner trim, wheel specifications, door-jamb requirements, clearance and service rating before installation. Owners of 18- or 20-inch 2026 4Runner trims should shop their correct wheel-size tire instead of either product above.
