I know its been discussed in many different ways on this thread alone but I still need a little advise. My car makes 770 rwhp. I currently have the M/T 20s. I have been using them for street driving as the stock tires are useless under 50 degrees as many have already said. I went to our local drag strip a couple of weeks ago & couldn't manage a 60' better than 2.1. I tried tire pressure from 25 psi to 11 psi. As my car is a manual I know that I certainly have room to improve my launch technique but when it jumps toward the wall on the 1rst to 2nd shift it gets a little scary. I have been looking at 17-18 options for a drag radial because I still want to drive it to the track. I might be missing something but I cant seem to find a 17' tire taller than 26.?" in a hoosier or M/T. M&H has one that is 28.?. Would I be better off with 17" wheel 26" tall tires or 18" wheel 28" tall tire. It seems to me that I would have more side wall & a bigger footprint w/ the 18 inch option. Any help is appreciated.

the 325/45-17 m&h drag radial is 28" tall and is super sticky. http://www.mandhtires.com/M-H-Drag-R...7#.UyeiqCe9KSM

I have those tires on Bogart 17x10" and they work well. Best 60' is a 1.53.

the reason the 20 inch mickey works better is because its TALLER than the 17 inch tire by a lot.. ts almost 30 inches tall... the 17 is 28 and its actually not even 28...

That M&H rear tire weighs how much? Is that 33 pounds without a rim? And by the way, that is the same rear tire that got me in the 1.4 60ft range also.... I think it works.

Weld RT-S 17's...ZL1

04-09-14 UPDATE! ok, most of you know I found a place I was VERY happy with purchasing a complete set at a what I believe the best price out there including the group buys... That was on Sunday. Tires arrived today and here they are. Couldn't help but weigh them. Not an official scale, but pretty close. The New MT front Sportsman S/R Radial 28x6.00R17's aren't that light, but everyone seems to be really happy with them.. and since I wont see the track but maybe a couple times I think for the street I should be happy?

17" Weld RT-s 71's with Black Centers should be here around May 7th.

Fronts 24.8lbs & 24.6lbs
Rears 33.8lbs & 33.7lbs

Wheels showed up today! Mocked up for wheel weights. ONLY 7/32" of clearance between caliper and wheel barrel on the front and rears. Plan on mounting tomorrow with low profile wheel weights if all goes well.


Front as shown 16.0 lbs on both floor scale and hanging scale.
Rear was weighed with hanging scale at 20lb 13oz


Mounted Rears with weights 55lb 9oz 26lbs pressure
Mounted Fronts with weights 41lb 9oz 50lbs pressure

Mounted Heights
Front-27 3/4"
Rear- 27 1/2"

Front Splitter is 1/4" higher

So will these rims work on our ZL1 rears for an 18 inch DR? If so it looks like a smokin' deal as a set of 2 are under $200

Please let me know thanks!
