Tire Size 265 70R17 Versus 285 70R17: Can I Use a Larger Size?

Before asking the question, "Can I use a larger tire size?", you should first ask yourself "Should I use a larger tire size?" Why is this important? While going to a larger size may give you that "big tire" look, changing your vehicle's tire size affects more than just cosmetics. Altering your vehicle's tire size can affect speedometer and odometer accuracy, handling, steering response and even safety issues such as tire load capacity. If done incorrectly, changing the tire size can decrease the safety of your car. If done properly, a larger tire size can be beneficial and even make your vehicle more fun to drive.   

Can you use a larger tire size on your car or truck? Depending on your wheel size, vehicle clearance and some other factors, there's a good chance that the answer is "yes." Our experts have decades of fitment experience and can point you in the right direction for your specific car or truck.

Is wider better? Often times, it is. We have found that many vehicles can benefit from an increase in tire width. In the post, "Wider Tires on Your BMW 3 Series?", we discussed options for upgrading tires to a wider size on this popular sports sedan. Using a wider size on the same wheel while maintaining the same overall diameter is known in the tire industry as "plus zero" sizing. It results in a wider contact patch for better lateral grip and an improved cosmetic appearance. This type of change in tire size can also benefit trucks, SUVs and crossover vehicles.  

What about going to a taller tire size? Increasing tire height can help to reduce unsightly fender well gap, increase ground clearance and in many cases it can result in a softer ride. While there are some exceptions, most passenger cars simply don't have enough clearance between fenders and suspension components to increase enough height to make a noticeable difference. Many trucks, SUVs and crossover vehicles, however, do have adequate clearance that allow for a taller tire size to be used.

How about using a tire that is taller and wider? Some full-sized trucks like the Ford F-150, Chevy Silverado and Dodge Ram can accommodate substantial tire size increases with both height and width. Let's look at an example of a popular increase in tire size with a top-rated On-/Off-Road All-Terrain tire. Check out the difference in size between 265/70R17 and the larger 285/70R17 size below.  


The larger 285/70R17 tire in the photo above stands over an inch taller and is nearly an inch wider than the 265/70R17 size. 

The larger 285/70R17 BFGoodrich All-Terrain T/A KO2 tire in the photo stands over an inch taller and is nearly an inch wider in total than the exact same model of tire in size 265/70R17. The width of the tread is also a half-inch wider. Many late-model domestic trucks accept this difference in size. Keep in mind that there are some trade-offs, mostly involving fuel economy and a reduction in loose snow traction.

My 1998 1500 2 wd truck has 275/60 15s on rally 15 x 8 wheels.
Look great, but truck does not track straight needing constant correction. Would changing front to 245/70 15s help with steering?
Thank you,
E Weber

Ernie, The narrower tires could help. I would have a shop check your alignment first and if it looks good then try the tires.

I have a 2006 Toyota double cab with 17in factory alloy wheels. I am currently running 265/70R 17's and am looking to go to a larger tire when my current tires need to be replaced (very soon) Will a 285 70R 17 work well with my truck?

My 2017 Mercedes GLC43 AMG uses 255/45/20 front and 285/40/20 rears. I have a set of Dunlop Winter Sport 3d's , 235/50/19 on your Sport Edition WX5 wheels left from my GLK 350.

I have a 2004 dodge 2500 Cummins WD. currently with 265/70r17 tires. Was looking at going to 285/70R17.
Thursday, November 30, 2017 by Tire Rack Team

Tom: The 285/70R17 is over an inch taller and almost an inch wider and may rub when you turn the wheel all the way unless you have a lift and/or fender modification.

My car is a 2014 AWD Charger RT. How wide a tire will fit in my fender wells on a 7.5 inch wide stock wheel?

I have an '05 Saturn Ion 2 with p195/60R15 tires. Can I use p195/65R15 or maybe p195/70R15 tires on my car?
Tuesday, December 5, 2017 by Tire Rack Team

Michael: 255/50R18 or 255/45R20 would be the widest that would work without some modifications.
Tuesday, December 5, 2017 by Tire Rack Team

Al: They are taller than we could guarantee to fit -- the 195/65R15 by almost an inch and the second size by even more. So when you turn the wheel all the way it is likely to rub.

Asking again: My 2017 Mercedes GLC43 AMG uses 255/45/20 front and 285/40/20 rears. I have a set of Dunlop Winter Sport 3d's , 235/50/19 on your Sport Edition WX5 wheels left from my GLK 350.

Can I use these on the GLC43 AMG?

Warren: The tire size 235/50R19 would be about 3/4ths of an inch shorter than stock so not recommended. The wheel will work if it is the 19x8.5 ET40, but you will need different lug bolts. You will need to call Seth at 888-541-1777, ext. 4177 to confirm the fitment and to order.

THE TIRES ON ARE 225, 65, R16
Thursday, December 28, 2017 by Tire Rack Team

Charles: We do not recommend mixing tires or sizes on a vehicle with the exception of wider rear tires on some performance cars. Even if it fit, the front now is taller than the back in your example which can cause issues with the traction control and/or ABS braking.

I have a 1997 k3500 dually currently running 235/85/16s. I'm considering a tire size change for the purpose of improved ride and the possible added benefit of increased ride height. My worry is that we use the truck specifically for pulling a horse trailer; would an increase in tire size effect my towing capacity/safety at all?
Thursday, February 8, 2018 by Tire Rack Team

Justin Langbein, generally speaking, the bigger tire would have more weight capacity so there should not be an issue that way. However, the tire size 235/85R16 puts you at 31.7 inches in height, beyond what we could guarantee would fit stock height if you have a lift on the truck you may need to consult the lift company for any taller options and advice.

I have chevrolet traverse 2014. The original tires size is 255/55R20 107H.

Can I use tires with the suze 285/50R20?
Friday, February 16, 2018 by Tire Rack Team

Ehab, that size would be a little bigger than we could recommend, it would likely rub when you turn the wheel all the way.
