what do you thinking about running a airdowned 315's in front and dual 285's in rear?

 

House-
I'm not a puller, but what about 285's in the front and dual 315's in the rear?

 

trying to achive wider front stance on a dually, there like 2.3 inches differnce in hieght between the 285 and 315 i dont know if it will afect the tcase or not

 

if you pull on pavement, DONT DO IT! however, if you are on dirt, you should be spinning your tires anyways, so whats it matter if your rears spin a little faster than your fronts? just make sure to take it out of 4 wheel drive before you head home!

 

I am not a big fan of running different size tires while pulling.

Have you thought about trying a 3/4 ton type rim like Coppess and Schinlaub do and run a 12.50 tire?

 

I agree with Justin, plus it looks cool too.

 

I am not a sled puller but what about spacers in the rear and runnin 315s all the way around?

Are there rules against that?

 

Jesse,
You guys coming out to Gaston tomorrow?

 

Hard tacky Indiana track and 2" tire difference is just going to = BROKE parts

 

the 315's are half woren out, and off ar 3/4 ton ford and i can use them free, and coppes runs diffrent size tires 285s and 33 12.50 16.50 the 315's are just .3 inch taller then the 33

 

Go for it.
Sounds like it might work well for you.

I was actually thinking of running different tires in the back and more aggressive up front to free up some wheel speed but have since decided against it for the moment.

 

Could you try single 315's at all four corners? If not , measure the actual difference in tire size - if they're worn enough and your rears are new enough, you might get away with it. More ideal would be 305/70/16's up front with 285/75/16's in back. Or if you go to 35's, then get something lik 35/14.5 fronts and 35/10.50 rears. JMO. Let us know how it works out for you...
