Tires

[Guest Anonymous]

I'm getting ready to start driving my 1982 280 zx that I just put a 350 in. It had the original turbo rims that were 15 inchers. What is the biggest tire I can put on the front. I have 135/60's in the rear, but they don't fit on the front. Any ideas, and or help???

Are you sure you don't mean 235 60's? I've got 225 50's on 15inch rims all the way around on mine I'm pretty sure (fron I'm sure at least) - no rubbing that I've noticed and my fenders are NOT rolled yet.. Not sure of the rim offset or anything but it's a Panasport rim if that helps - most liekly 7inches wide. The tires seem a bit short to me and I've been pondering sizes for a 16 o 17 inch rim.

 

Anyway, not sure I can answer your question but I found a formula the other day that might help a few of us with these kinds of questions. Trying to figure out plus one and other sizes was driving me up a wall - this formula should help! It's from this month's Popular Hot Rodding

 

(width(mm)XAspect RatioX2)divided by 25.4+wheel diameter=tire height

 

For example: 275mmX.40 (ratio)X2divided by 25.4+17=25.6 inches

 

That's for a 275 40 series tire on a 17inch rim. I ran the numbers on my combo and compared it to the height Mike Kelly told me his was - yup I'm a bit shorter than his. I bit taller tire would be good for me I think as it'll keep me off the speed bumps. Figure for each inch taller I'll get a half inch of ride height.

Yes, I did mean 235's. But they won't fit on the front with the stock 15 inch rims from Nissan. I'll try 225/50s as well. If anyone else has any info, I would still love to hear it.
