Can I put 35 inch tires on the stock wheels that came with my 08 F250? They are 20 inch wheels, but I'm not sure how wide they are. Stock tires are 275/70R18. Thanks, just doing some window shopping on the net, curious if I need to spring for new wheels too. Gonna add an Icon 4.5 inch lift.

, pretty obvious I know nothing about this stuff. Glad it's good for a laugh. I'm just trying for some help here.

 

I laughed...... that's almost sig worthy

Seriously though, 18s or 20s, you should be fine if it's a 12 to 12.5" wide tire. I don't know why you want that big of a lift for that small of tires, I'm pretty sure on the 08+ trucks 35s fit without a lift. I'm running 34x12/18s on my 07 without a lift (heck, factory 20s come with 34" tires) , and several guys have run 35s with only a 1" spacer. 35s are gonna look tiny if you lift the truck that high.

 

On stock rims you can fit 35x12.5x20. If you are running an aftermarket 20" rim with a different offset you may or may not be able to fit them without rubbing. For the most part, any rubbing would be under turning at full lock... and for me that rarely happens. My stock rims have the Goodyear Wrangler A/T tires that are 275/65/20 on them and they measure in at 34.1 inches tall. I purchased the Mickey Thompson Baja ATZ tires in 35/12.5/20. Their overall height is 34.4 inches... so that is not much of a change.

 

I run 35's on my stock 17in rim

 

Got pictures? Running a 12.5 wide tire on your stock 7.5" rims? Any problems with tire wear?

 

texastech_diesel is right - I have 35's on my '08. They looked fine at stock height but I installed a 2.5" leveling kit and now they look too small. As soon as they're worn, I'm going to 37s!

If you're putting on a 4.5" lift, they will probably look even sillier. Save your money and buy 37" tires AND new wheels!!!

Can you run 37" on a truck with only 2.5 inch lift? I think the 35's look pretty good in that pic. Any issues with drive train wear, power, and milage decreases with the 37's?

 

I have no experience as yet - I know there are guys easily running bigger tires than 37s. ReadyLift advertises that 2.5" kit to allow 37's on the '08 and up Super Duty and in person, you can see there's plenty of room.

As for wear and tear, I don't think these trucks have to worry. They are plenty heavy duty enough to handle it.

Mileage - I went from stock tires to the 35's and saw no difference. The increase in circumference should reduce the RPMs on the highway and either offset the extra size or even increase highway mileage.

 

35s clear on stock offset wheels, just get the sawzall

 

I like the website in your sig. Good information, for sure! I'd like to find a similar discussion of a build for an '06 F250. I guess that much of what you did is applicable to the '06 as well though.

 

I ended up ordering an Icon 2.5 inch leveling kit. I spoke with one of the tech at Truck Toyz where I ordered the kit, he said they install 35x12.5 on stock 18" wheels all the time with no problems. This an 08, 2.5 inch leveling kit, 35"tires. Stock wheels, tho they are 20 inchers.

 

Here are my new Mickey Thompson ATZ's 35x12.5x20 on my stock rims and suspension, I think they look great, and they are extremely quiet for a MT tire.

 

I was wondering will 35 tires fit without modifications with 18 inch rims
