what\'s the deal

O.k, I have a 2.2L, 2wd, Sonoma , I want to put bigger tires and a body lift. I was under the impression that 235 were the biggest i could put on the truck stock, and that 30x9.50 were the biggest I could put on with a body lift. Yesterday when I went to the dealership i asked them and they said that I could put 31's on stock. The guy said it would rub when I made turns but that it would work. Has anybody had experience with this? What is the biggest size I could put on stock, and what is the biggest size with a body lift? He also said if I change the stock rims to 15x8 it wouldn't rub as much.

thanks

Re: what\'s the deal

I had a `92 S-10 4x4 with 30x9.5's on it. That was about all that truck could handle unlifted. I run 32x11.5's on my `96 ZR2 now, which originally came with 31x10.5's. I don't see how you could fit 31" tires onto a 2 WD (2WD's normally sit lower than 4x4's stock) without AT LEAST 3" of body lift. My ZR2 has 3" suspension lift and the 31's barely fit... 32's rubbed A LOT until they wore down a little bit.

Aside from the fact that you'll have a hard time fitting bigger tires onto your truck, the acceleration and fuel economy your truck has now will go to pot for two reasons...

a)the rear differential gears are too high for the bigger tire size. (I run 3.73 gears on my ZR2 with the 4.3L. 2 WD's are normally 3.08, although I have seen some with 4.11's. If you have 4.11 gears, you might be alright.).

b)However, the 2.2L engine is too small (not enough power) to bring you up to speed with big tires and the 3.08 gears you probably have. This means the engine has to work harder just to bring you up to speed, requiring more gas.

Just my $.02

<font color=red>TOO MUCH POWER</font color=red> isn't enough.

Re: what\'s the deal

Look in your glove box and find all of the three digit codes that start with the letter G. like GU6 or G80...,I'll get back with you and tell you what gear ratio you have. It will be important if you want to run bigger tires.[img]/wwwthreads_images/icons/smile.gif[/img]

Re: what\'s the deal

O.k I looked in the glove box and the only 3 digit code starting with G is GT4.

Re: what\'s the deal

The GT4 is a 3:73 ratio, pretty common for a 4cyl. I wouldn't put too big of a tire on your truck. Hope this helps.[img]/wwwthreads_images/icons/smile.gif[/img]

Re: what\'s the deal

thanks, if I do put 30x9.50 on what gear ratio should I change to? I won't be able to do it all at once but I'm hoping that after 2 or 3 months I can afford to change the gearing. I think I should be o.k with 30's for that short time.

Re: what\'s the deal

4.10's would bring you close to origional gearing (assuming 205/75R15's now).

3.73's and 30's will be torerable, it will still be quicker than what I have..but what isn't?
Answer: geo metro, tracker, old 4 cyl Toyota's and bronco II's, that's bout all I can think of now. [img]/wwwthreads_images/icons/frown.gif[/img] But I got my eye on my neighbors tempo, I think I'll have another kill as soon as I get the chance. [img]/wwwthreads_images/icons/laugh.gif[/img]
