Hello I have a jeep wrangler unlimited and am getting 35s with an 18in rim
This is my daily driver but I want the tire to run true to size unlike the km2s
Thanks cameron

 

That is almost impossible. Tires will always get "smaller" with the weight of the vehicle on it.

Super Swamper tires are known to run true to size or slightly bigger unmounted. But once mounted, it will be below 35".


If you really want a 35" tire mounted, might as well buy 36s or 37s that will run 35" when mounted with the weight of the vehicle on it. Your best bet is to read on the spec sheets to see what size the tires are unmounted. The KM2 seems to be 34.8" which is an average size for a 35x12.50R17 tire. The 36s and 38s seem to run a half inch smaller.

 

pitbull radials run true to size as it gets. if you want a 35 km2 just buy the 37's and you got what you want. km2's are the best combo (dd or offraoad) tire i have ran and will most likely go back to them in a year when i change out my tires agian. they are fairly quiet and have great on road manners. they are also a great offroad tire in the rocks and mud. i ony run mine about a year and sell them off. currently i am running a 37 (36.5 on the jeep) pitbull rocker and while they are great off road they lack the nice road manners i would like in a dd tire. if i could get them to ride better my opinion might change even with the b52 bomber sound.

 

Toyos are bang on or a little bigger.

 

thats not true u can always just run high air pressure if need be
my 37" mtr's w/ kevlar are true 37"

 

Pitbull rocker radials were a hair off 37"s with weight on them, i imagine the same could be said about 35's

 

I second the mtr's. My 37's feel like the 40's I used to have on a different vehicle.

 

x3 on the MTR/K's When I pulled up next to another JK with 37" KM2s they looked the same size.

 

What about for 18 inch rims with a 35 inch tire

 

To find the true tire height why don't you measure the circumference and divide by PI (3.141...?), I believe that's the right formula. Say you have a true 35" tire (110" circumference) but when you mount it, it only measures 34" from the ground to the top of the tire, you still 110" circumference that your axles have to turn. I'm by no means an expert, but if you plan to regear I would think about that before getting a 37" tire to achieve a 35" tire height.

Sorry if that's confusing.
