I have been running the MT 32x16 102" roll out they weigh 42lbs. If I would switch to the 33x10.5W how much if any ET should I expect? I have some quick 16's that I run and sometimes a few hundredths would make the field. Would the smaller tire have a shorter life span than the big slick? I have 2 sets of wheels so could switch around easily. Car weighs 2450lbs, run a conv headed 632 1.65 low gear glide 4.86 rear gear. Car runs 5.0's @ 137 with this setup.

Well 75 views and no answers.

I will say that I don't think it will be much going to a lighter tire but a larger circumference. Unless someone had a set up really, really close to yours and has done this exact change then it is just a WAG at best.

Apparently this is not a popular change I think the rollout would be about an inch more but I assume the 10.5 wouldn't grow as much being on a 15" wide wheel.

are you bracket racing or 10.5 racing? MT doesn't make the 32-16 anymore either...

Bracket racing, just need a few numbers occasionally to make the field for some local Q16 races.

MT started making the 30771 32x16 late last year again and now I see they have also started back up with the 3080 33x15 which was my original tire of choice.

Good to know i was confused when they stopped offering the 32-16

There are alot of tires that were not made shortly after the Goodyear acquisition. Most all of them have been brought back now. I run a 3080.

Small shot of nitrous.

Ya I've been considering that but I've never messed with the stuff and afraid I'll blow the heads off it
