Zero and don't plan to...I hate being around traffic. The only time I get off this road is to get the annual inspection. Driven in TX, you'd prob want to use higher tire pressures for those roads and speeds. MG did poor job mounting the oem tires, although they were a little lighter than the RoadTecs, they had a ton of weights on them. I mount/ balance my own, and balance the wheel first marking location and weight, then remove weights and put heaviest part of tire on lightest part of wheel I used less than 1/3 the weights that were on it. Sometimes it takes less weight than it did to balance just the wheel.
