What size tires
 

I just purchased a pair of weld draglites and I was wondering what size tire should I run? I have 4.10 Gears in the rear(automatic) and the stock tires right now are 225 60 R15. I was wanting to go to 255 60 R15 or 255 50 R15. Which one do you guys and girls think i should go with?

Also I was wondering if anyone knows how far my speedometer is out with the 4.10 gears.

Thanks for any help:)

I'd probably go with the 255/6015's

Another vote for 255/60/15. ~Brian

I run 265/50-15's on the rear and they fit well. I'd say get some 26x10.5 15 e.t. streets.

I think I'm going to go with the 255 60 R15 for the back and 195 60 R15 for the front.

Does anyone know how much my speedometer could be out with the gears I have. I know it is two questions in one but I have never figure it out and I was wondering if someone knows off by hand.

The car is an 88 Automatic that came with 2.73's from the factory(now has 4.10's).

Any help would be greatly appreciated

speedo difference
 

I am running 4:10 with AOD, 26 inch tires and it looks like I am off about 15-20 mph slow. I didn't go to the trouble of changing the speedo gears as I don't drive it much on the street. Hope that helps.

Thanks for the info Barry Jackson.

It is good to know how far my speedometer is out
