roll out is measure to make sure you have matching tires, a smaller tire on one side will cause the car to pull because it will be rolling faster than the other.

the DIY was is to Place a 1" white line on the tire and mark it's position make one full revolution with the tire, take a tape measure and measure the ditance.

At large Event's you can usually buy matched tires from the MT trailer

 

No problems. Looking back on what I wrote last night it did not come the way I ment it. One to many beers. sorry LOL

We can go over the rest then. I have faith you can make it hook

 

BTW Many times they have the number on them in white across the tread when you first get them

 

Most MT tires i have seen are not marked, the tires need to aired up to do that. If a retailer is doing it local to you thats very nice, doesnt happen around here.

Hoosier does mark theirs at the factory so they can be matched.

You can buy a tire tape and just measure them or a piece of string and mark it (metal carpenter tapes dont work well, not made to go around curves) then just air the smaller one up a little at a time (putting it out in the sun speeds it up) until it gets to the right size. Then put both tires at the same air pressure and check again, if its with a 1/2" or so just leave it. Only works with new tires.

MT has the procedure on their website under tech stuff. Also nevr ASSume just because the same number is written on both tires they are the same when they are mounted on your wheels.

 

Ok that would explain it. I am using hoosiers and have seen Nitto's marked also

 

Most radials on modern molds are a non-issue I would think, the bias tires are the ones to watch I would assume. Maybe someone who has gone through afew MT radials and checked them can chime in and see if they need to be checked or not.

 

This was on the Nitto 1320s They were off quite a bit on the first few batchs we got last year

 

I have had only one set of 275 MT radials and one set of 325/50/15 MT radials and they were both exact. I just figured new molds and tighter tolerences, plus being DOT, would keep them a little tighter. I'm not familiar with the 1320 Nitto, drag radial I presume?

 

My MT DR's are good too.

As well as they hook I don't think I'll ever hassle with slicks again.

 

I'm pretty sure the MT radials are pretty close, if they werent not to much you could do at home.

I just use drag radials because I have to in some races. Maybe I'll grow to love them some day I just wish they would make a 305 something that was 28.5" tall..

 

KP sorry have not had time to look them up. grab one of your FSC's and look them up It is Nitto's new drag slicks

 

Yeah, that would be nice.

 

I didnt even know they were making slicks, I seen the 1320 thing but never read past the 1320
