My buddy is building a diesel Dodge for drag racing. He was just talking about a supposed diesel drag radial coming from Nitto very soon. Anyone with first hand knowledge? Isn't there somone on here that works at Nitto?

Later, Bruce

why do you need a bespoke radial tire for a diesel?

exactly why would you need a tire specifically for a diesel application? Tire contact patch to racing surface should have nothing to do with the fuel type...am I correct?

the only thing I can think of is the weight of the vehicle...maybe they need stiffer sidewalls?

Height may be an issue as well. Diesels tend to run really tall tires and they just don't make DR's that big. I think the weight/sidewall has something to do with it as well.

sidewalls for the drag radials on my dads chevelle are bigger than the ones on his avalanche.......

Height is an issue and classing is also an issue.

It is going to be a truck tire size I bet. And with all the torque and the extra grip of a race tire, you would think that they would have to possibly do something different to prevent the tire rotating on the rim.

I doubt the torque seen at the wheels is drastically different since a diesel has to be geared taller to make up for the lack of revs.

I'm voting for truck tire size.

You sure? Have you driven a diesel truck?

It is significantly easier to rip the tires loose from the pavement in my diesel truck than any gasburner I've ever been in.

Diesels are known for their towing ability not just because the stump-pulling torque ends at the flywheel.

I'm going to agree that the fuel in the car has nothing to do with the tires. I'm guessing the tires are kind of getting an industry nickname of "diesel tires" for the combination of truck sizing and the fact that LOTS of people are now adding performance tunes to diesels, which leads to the need for DR tires. They'd work fine on gas burners, but not too many people would need them.
