Eibach Pro-Truck Lift Tire Size
 

Was looking at the Eibach Pro-Truck lift since there is a group buy going right now. I'm currently leaning towards the Dobinson setup (was actually about to pull the trigger before COVID craziness), but thought the Eibach deserved a second look, especially since their springs are so well thought of.

I know a few people are running this setup on 4th gens, but haven't seen anything about tire sizes. Those that are running it, what sort of tires are you all using? Curious as I'm seeing lots of conflicting info as to how much lift their 2.75/1 kit actually gives.

Your choice of a suspension brand wouldn't affect the choice of the tire size. People that are lifter with Dobinsons can run the same tire as people with OME, bilstein, etc. If that is what you are asking.

In terms of what size -- there is a philosophy that lift doesnt change the tire size but no one like to hear that lol so I amma quote the 1st post of the suspension FAQ

Front/Rear Lift Tire Size

285/70R17†
305/65R17† (32.6 x 12)

I guess you can assume you would get at least 2.5" so you can go with 255/75r17 or 275/70r17 safely (or whatever is their equivalent for 18" rim).

If you are going bigger/wider than I have noticed that its very YMMV. Most people need BMC for 285+

Something else to think about is the weight increases with tire size.
You can effectively double the weight from stock to 285 size.
Seems like that extra weight kills stock like suspension stuff faster.

I was planning on sticking with a 265 or 275 tire width regardless due to weight and clearances. I guess I was just looking for some real world examples of tires people have run with that lift. The fact that the front is 2.75 and the rear is 1 is throwing me as that's more difference than is typical.
