What size slicks?

Chris_H · 08-30-2003, 10:08 AM

Well I finally have the money to buy myself a set of new slicks. I am currently running, of all things, Goodyear Stock Car tires for my slicks. They were $30 so I couldn't complain. I have actually seen 1.80 60' times on these. I figure with a real set of slicks, I can do some damage at the track and get my times down even further, and hopefully not break a 16 year old axle!! I am running the same trap speeds as a buddy of mine with my 13.4 @ 102 and he is running 13.1's and 102 with 1.6 60's. Granted we are at 4,100' ft, so our times are quite a bit slower than most people's.
I am trying to decide whether to get the M/T's in a 26x10x15 or go with the 28x10.5x15. I have 4.10's right now, and dumps so I don;t have to worry about tailpipes being in the way. Would the 28" make a big difference with my 4.10's? Not sure exactly which one to go with, so I thought I would ask you guys. Any help is greatly appreciated.

Without a doubt... the 28x10.5 is too much tire unless you have well over 600HP

For example, the NMRA R/S cars are limited to 26x10 slicks and the majority of the class runs in the mid-low 10 sec range (a few guys recently entered the 9's).

In contrast, the NMRA Renegade cars are limited to 28x10.5 slicks... with most of the class running in the low 9 sec zone, with one guy in particular (that I know of) going high 8's.

You may even want to consider the next size down (26x8.5???).

What width is your rim?? Alot of guys are running a 9 or 10" rim with the 26x10's to maximize the footprint. I use a 15x10 Bogart with my 28x10.5's. The 28" tall tire would kill off alot of your gear too.

I would go with a M/T 26x8.5 slick for your combo...

I am using the stock 10 hole rims. I have used the 26x8.5 that a buddy has, but didn;t know if I should with bigger, or keep the same size. Just found out a buddy wants to sell his Roush 180's for $400 so I may not be buying the slicks....

I have 4.30s and I use a 26 X 9 . I can 1.5 60ft. I am quite happy with them.

So your saying you use 5th gear in the 1/4 mi?

Yea, i run 26x8.5 m/t on 15x8 weld, i dont have alot of gear, but they will take just about anything i give them on 10psi of air.
