My car consistently 60's in the 1.43-1.49 range with the MT 26x10 stiff wall, 5-6k launches as well.

A 10" wide tire on an 8" wide wheel is not an optimal combination. Probably your issues with the MT slicks.

 

My car did a 1.39 off the transbrake on the 3053s with the smack turned all the way up. Usually does 1.50-52 on an 11.00 tune up with either the 3053s or the 8.5 Hoosiers.

Both on 10" rims. Never had trouble hooking on either tires, but like the way the 8.5's look on my car compared to the 3053s. If you are going to have a slow car, you might as well have a small tire.

Runnning the baseline suspesion rear with QA1 adjustable shocks. 70/30 with coilovers up front.

 

Thanks for the input fellas. I am worried going to a 10inch rim with the MT 3053s will make the sidewalls even stiffer.... Perhaps a 10inch wheel with a regular set of MT 26x10s would be more suitable. What do you think?

 

What RPM were you launching at with the Stiff sidewall? I saw your post about being worried about using the stiff 10" on a 10" wheel and thinking it may bite harder. I am not sure if this may happen, it may even work better because it fits the wheel better. What about trying this and just keeping the tire pressure higher and adjust it until it just spins a few rotations? It would be much more stable too on the topend. I think I would rather have a tire that hooks too hard and have to keep it from bogging by using a higher tire pressure or maybe a higher launch RPM. Most the time the tracks dont have a very good prep unless it is a structred race.

 

Launching at 5000rpm, have them pumped upto at least 17psi to avoid dead hook. Sometimes more to get them to go around a couple times. It has been my experience that excessive dead hook brakes parts. At only 115mph top end stability hasnt been an issue with either tire. I suspect at higher speeds it would become more apparent..... I am really struggling with this decsion.....

 

While a 10" tire on an 8" wheel isn't ideal, I personally haven't seem any issue with consistency running both the 26x10 and now a 28x10.5 on an 8". Don't forget that if you change tire sized you also change your gearing. A 26 tire with 410's is about the same as a 28 tire with 456 gears. I think you need more rpm on your launch. My car is(was) about the same performance wise as yours, and I launch between 5800 and 6400 depending on track conditions, with 12psi in the tires. 60 foots for me are 1.52-1.56 range on most tracks.

 

Thanks for the input everyone. I am going to pickup at set of 10 inch rims and mount some Mickey Thompson regular 26x10's on them and see what happens. Worst case I will still have the stiff sidewalls mounted on the 8inch rim in the trailer ready to go.

 

bumping this..

anyone running 26x8.5 slicks on stock 15" 10 holes? also does MT make a stiff wall in that size?

 

I use a taller tire to increase the contact patch or footprint.

I have a soft sidewall MT slick 28x10.5 on an 8 inch rim with no tubes, and it dead hooks at 15 lbs even at 5000 RPM launch. I only used them two or three passes, because the driveshaft bent and the axle tube welds broke.

The closest other tire I have to them is a M&H radial. It's a 275-55R16. Although they say 9 inch rim, the guy M&H assured me it would be OK on an 8 and it is. The MM&H are about a second faster than my MT ET Street 27-10.50 tires. The MT ET Streets just blow completely off when I shift into second and won't recover, so I have to get off the throttle at the 1-2 shift to make them work.

Contrary to what others find or report, mine works great with a soft sidewall. MT says the sidewall should be stiff, the guy at M&H says it should be soft. So far, the guy at M&H seems to be correct for my car.

 

A 8.5" slick will work just fine on a stock 7" rim (10 hole or turbine)...I ran several sets that way..and a set of 28x9"s on a 7" wheel.
I run a set of Hooiser 26x8.5's on a 10" rim. The Hoosier 8.5's are even stiffer than the M/T 26x10 stiffs. Outlaw 8.5 guys have gone 1.1x 60's on them....they work and can hold alot of HP. Don't be afraid to run higher air pressures with them to get them to work on your car. Each of the 3 tires are different as far as what tire pressures they like. I weigh 3300# and run ~16psi depending on track conditions.

Up the launch rpm. Tires around 16. Use launch rpm for track conditions. The 8" wheel will work but 10's are better.

The stiff tire was build for stick cars.

Nmra coyote stock racers are using 26/10 stiff pure street and real street cars were also.

I was going to suggest the Hooser 26x8.5 since that is what pretty much all the guys were running in the Outlaw 8.5 stuff. I have several buddies that were running 8.5 when it was big here in TX, every one of them was on at least a 10" rim, some on a 12" rim, and one of the top guys actually had an 11" rim built and liked it the best on that tire. Kenny Hubbard is his name and it was his Orange Nova at the time. Can't argue with 1.1x sixty foots on a baby tire.

I say go with 10" wheels for 26x10 or 26x8.5. Car will be more stable and the contact patch is better on the tire.
