Another Dumb Tire & Wheel Combo Questions...

[Boss X]

Ok, I finally narrowed my choice of wheels down to a couple models. I'm going to replace my factory 15" mag with an aftermarket 15" mag and either a 245/75/15, 255/70/15, or 245/70/15 tire (probably the Pirelli ST). I will also be installing new twin tube IAS shocks.

In any case are there any problems with any of the above combo's? Clearance, etc?

What "offset" will I require? Dealer seemed uncertain.

Will I need to recalibrate if I go to a 70 series or any of the above tires?

One of the wheels I'm looking at is an aluminum, welded 2 pc. wheel. Are there are problems with this type wheel? Is stength or durability an issue? I drive 99% highway, rarely off-road. Jersey roads suck.

Give me a classic 1960's something vehicle and I can do everything but rebuild the trans. These new cars are just too dang techno for me and my limited tools. Oh, well I'll get used to it someday, maybe!

BossX, I think any of those tire sizes will work. The 245x75 will be slightly taller than stock, but should do fine.

Your stock backspacing is 4 5/8", on a 7" wide rim. This gives an offset of about +5/8". If you're looking at aftermarket, I assume the wheels are 8" wide? If so, I would recommend a backspacing close to 4 1/2". This will give an offset of 0"; close enough to stock to reduce any unwanted handling characteristics, and give enough room to prevent rubbing.

Yeah, I know what you mean. IMO, the last "real" car that Detroit ever made was a 57 Chevy. Stick with this FI stuff long enough though, and it'll grow on ya.

Come on guys (and gals) as the case may be. I need some help here. The dealer for the tires isn't offering any real help and the dealer for the wheels is if no help. Tried other sources but get the same response, nothing.

I want the 255/70/15 or 265/70/15 setup (maybe 245/70/15) but I don't want any problems after getting them. Its as if the dealers don't want to commit to anything on a 4x4. HELP!!!!!!!!!!!!!
