Tire size

I now have LT 275-65R-18 tires on my 2011 tundra have a chance to buy 275-70-18 tires at a great price. what is the difference?

 

+1.1" diameter and a little narrower.

 

Depends on the tire, I am researching that size right now. For instance Toyo lists the M/T as 33.6x11, the AT2 and RT as 32.2x11, Nitto lists the Trail Grap as 33.62x11.1, and the Ridge Grap as 33.19x10.98. I think the difference in height on the Trail vs the Ridge is the Trail's tread depth is 19.1 and the Ridge is 16.4

 

Which tire are you saying is narrower? Both are 275 so wouldn't width be the same? The 65 vs 70 is the sidewall so that would be the difference.

 

so the 70 is 1.1" taller?

 

Roughly yes, like I said it depends on the brand. Go to the website of the tire you are trying to buy and it should give you the specs.

 

thank you very much
