Greg,

They are 7.50 x 15's and I don't remember the brand, I am in the house now out of the heat, but next time I go to the shop I can check the brand.

They are dot approved tires....Bias

They ride good with very lttle air in them, remembering they are for trucks and trailers with a high weight rating which we don't need so I run 8 to 10 lbs in them all the time and they ride good, makes for a bit of a stiff steer.....

In the dirt they work awesome in my opinion, it will give you and idea on how they work if you take out your own produced video where you guys are coming down that steep hill at the Majave run, watch JayManx's buggy come down and watch the front tires, they don't move.

That's my 1.8 cents and I am sticking to it.....:010
