Update on the M/T radial front runners. I had to return one of the tires it had a small bulge in the sidewall. The replacement is mounted & on with no issues. Hope to be testing them soon!

No issues with the radial front runners this past weekend!

While I have the car calmed down for the most part on the big wheel stands. I did run one pass in some decent air at the bracket finals. We had a high/long wheelie the car landed very nice & smooth. IMO, these tires are smoother than the bias ply front runners.

The time slip is what went with the run, just because people like time slips.

TTT, these tires are still sweet! The wear on them is nonexistent compared to the bias front runners. They have a noticeable smoother/better ride thru out the run.

Now that I have more laps on these MT-3850 ET street front radials I find them to be superior to the lightweight bias I was using prior. The front of my car steers straighter and feels more stable in bumpy shutdowns. Although radial is 5# heavier than same size bias, car runs exact same numbers. I wouldn’t return to bias fronts given the choice.

The availability of these MT radial fronts is surprisingly low and I waited two months to purchase. In less than five days they were again sold out.

I'll be going to this size when I have to replace mine. If I remember correctly, mine are the 3851s & are 27" dia.

fyi, my MT-3850 on a 15 x 4 wheel at 35 psi measured 25.5” tall when not mounted on the car.

Have you noticed any difference in reaction times, going from bias to radial? As I recall, in a bias ply, lowering air pressure helps slow down r/t a little. With typical radials being stiffer, I'm also curious, how varying air pressure may affect quickening or slowing down r/t.

This MT-3850 radial is 3/4” taller than the previous bias fronts. Using the exact same delay. I set my front tires at 35 psi off the trailer and don’t monitor or change during a day event. Same when I no-box race.

I've played with the pressure a little, the same follows as the bias but not to the same amount.

Thanks. My bias fronts leak down fairly quick in my opinion. 1-2 lbs every few hours, so I keep an eye on them every few passes. Been planning to replace them, just not ready to spend that $$$ yet. Considering going to radial, as long as the weight considerations don't count them out.
