Tire Sizes For Rallies?

[armybyrd]

My '83 stepside has the factories rally wheels with the 235/75/15. Id like to go a little wider for new tires. What sizes am I able to go with?

[gchemist]

275/60R15 are a nice fit. They fill in the wells very nicely.

['79squared]

I'd say 255/60 front, 275-295/60 back. My backs are 275/60's fyi.

on my 82 the reaer has 295/50/15 on 10 inch wheels and the front has 235/60/15 on 8 inch wheels

I'm hopeing this size works for me in the 79

235/70/15 and 275/60/15 are 28" tall.

235/75/15 and 255/70/15 are 29" tall.

Either will look good at stock height. All will work on a 15x8 rim.

It's when you go less than 28" tall that the tires look a bit small without a lowered ride height. 26" and 27" tall are often used on cars but look good on a lowered truck.

how wide are the stock rallies?

Thanks 88Jimmy, I'm a sucker for stock trucks.

[88Jimmy4x4]

if your truck is stock height or just leveled, get 255/70/15 all around, otherwise you will have way too much fender gap for the smaller dia tires listed above

I agree..I have a 30" tire with a 4.5-5.0 drop and anything smaller looks like it would create a big gap.
A 255-70 is 29.1" tall

I disagree. The 275/60 which others (and myself) prefer are within .2 of an inch in height of the stock 235/75 tires in height. That's too close to even argue about. Heck, the 454SS trucks came with them from the factory and they looked real good at stock height.

you need to check your math

235/75/15 = 28.87 (235/25.4 x 75% x 2 +15)
275/60/15 = 27.99 (275/25.4 x 60% x 2 +15)

Thats closer to 1" shorter tire

I know about 454ss, heres mine

I agree. The 255/70's are a perfect fit for a nice clean rally wheel and stock ride height. Search around this board a little and you'll find quite a few with 255/70's on that look perfect.

[statiC10]

I run 235/70 in front and 275/60 in the rear. A lot of people use 255/60s up front, but I think they're too short. Not a fan of extra wheel gap.

[Buzzman]

Depends on what look you're going for, but here's a fairly stock setup:
235/75/15s on 15x8 Rallys sitting at stock ride height...

[88Jimmy4x4]

I love your truck Buzzman, looks great just as it is at stock height...perfect

[99-LS1-SS]

I ran 275/60 on my 8" rims and I thought it looked good.

[PAWS 72]

Even though it's a 72,255-70-15 on 8'' front and rear.Hope this helps.
