Street tires? Drag radials? DOT's? Front and rear? Rear only?

heres what ive got on my car. 15x5 FR and 15x10 RR Weld Pro Stars. 185/65 FR rubber and 275/50 Nitto DR's RR.

that's about the widest tire you can get without getting a taller size. with my stock 2.73s, a 26in tall tire is more than enough (which is what the 275/50 comes to). with your 4.10s, you could go with like a 325/50 or 345/60 which are like 27.5 and 28/29 in tall tires if you wanted.

as far as the wheels, i had to grind about an 1/8 in. off the back side of the caliper were the little "gills" (for lack of a better term) are. it wasnt much at all. took about 10min total and was done with a little hand held rotary grinder. other than that they work fine. no moding on the FR, just need spacers.

i dirve on mine every day and havent had any problems yet out of three months of driving.



good luck, jon

You don't have a lot of choices in BFG DR's....

275/50-15 - 26.1" Diam, 11.3" section, 10" tread, 7.5-9.5" rim

255/50-16 - 26.1" Diam, 11" section, 9.7" tread, 7 - 9 rim

The 315/60-15 or 345/55-15's are almost 30" diameter and won't fit.

That puts you into a 15x8" wheel, 5.5" backspace. Most 15's require grinding the fins off the rear calipers, but not all wheels present this problem. The Weld Pro-Starts and DragLites do.

For the 16" DR's us a wheel similar to the stock 16x8 5.5 to 6.5" BS, and you will be fine, no grinding.
