I would look into what level of ofter market suspension you got. Because 235's should be fitting with no issue at all.

If you do decide to get a body lift the best kit is the PA 2 inch lift. it comes with decent instructions and the price is not bad at all. you can find it on amazon, ebay, and jegs/summit racing.

 

Non ZR2 had two suspensions: standard, & firm ride. RPO codes in the glove box that start with "Z", will tell which suspension the vehicle was originally equipped with. Post them and we can figure out which suspension you have. Capacity of the rear springs is different from standard to firm ride and the torsion bars are computer picked just prior to vehicle assembly, (depending on what options the vehicle has). You will be able to adjust front chassis ride height to factory specs no matter what bars were installed. Once it's within spec, the difference in ride firmness has to do with the tempering of the steel in the torsion bar. As mentioned earlier in the thread, incorrect ride height will cause excessive wear to steering linkage and suspension parts; adjusting the torsion bars, even a little bit, causes a substantial weight shift that affects camber, caster, and toe adjustments. The main thing is to get chassis ride height within spec to reduce wear on the parts. Next step is get a wheel alignment to prolong tire life, then leave the torsion bars alone If you install a lift kit, make it a body lift, and do it before adjusting ride height & the wheel alignment. Might not hurt to check rear ride height as well.

Captain Hook, Thank you very much for al your help, I really appreciate it. Indeed I double checked & you are right & as I thought, the door jamb does list the 235's as normal for this vehicle. I am not sure what this tire manager was after. The 235-75-R15 Michelins that I had installed fit perfectly fine. However, she stated that they would exclude the Michelin warranty on the tires if I either did not get a leveling kit to raise the vehicle some at the front or got rid of the mud flaps. As they could not get ahold of their leveling kit source & I needed to get the tires I let them remove the mud flaps for now. Hopefully you can give me the ok to just tweak the torsion bars a bit to get it to factory specs as I would swear & my wife agrees by memory that the ride seemed to drop after FS did their work on it about a year ago. I do not have an aftermarket suspension on this vehicle at all. Everything came from the dealer or the mfr. I will check those codes as you advised in the glove box in a bit & look for my sticker as well as I am sure I still have it since I typically keep all of that stuff & I will re-post later to let you know. Thank you again, I really appreciate it.

 

Also as I mentioned earlier as well I am certain Uniroyal 235s were on the vehicle originally from the dealer & with the mud flaps installed by the dealer. Then I had that blowout at the left rear going down I-10 several years ago & in a pinch I had to get the 205s which seemed slightly smaller & I wanted everything to match & they had no 235s. Besides the fact that the 205s now at this store would have been special order & cost more slightly believe it or not, I really wanted to get back to the way it was as I felt the 235's just seemed "more right", pardon the phrase.

 

Captain Hook,
I got the numbers you needed & I hope I got the right ones. The window sticker also said we had the premium Touring package. My apologies as I thought it was a different one as I recalled. We do have a lot of extra off road & heavy duty type stuff that was part of the package. The main number in the glove box is 1GNDT13W7X2208154. The Z type numbers are as follows; ZBG, ZM5, ZM8, ZQ3, ZQ6, ZY7, & Z85. Let me know if you need anything else & I will do everything I can to help. Thank you

 

Adjusting ride height is something you can do, but the vehicle must be on a level surface, front to rear, and side to side. Specs are in the link in post #6, and they are the same for yours.


Z codes:
ZBG = 235-70-15 tires were original equipment.
Z85 = firm ride suspension, (stiffest torsion bars of any T series vehicle).
