What tires to go with ?

[Marvin9075]

Hey guys so recently bought a pretty nasty 03 cobra . Has a 3.0 whipple on E85 with over 700 Rwhp. Right now the car is sitting on 18x9 rovos wheels that I am not a fan of and I am looking into getting black deep dish 03 cobra wheels with a 17/10.5 on the Rear . My question is what tire do you guys recommend to use . This is a weekend car that never sees rain and the current 305/35 Mickey Thompson ET STREETS don’t hook very well . What do you guys recommend ? Should I just go all out and do some race stars with drag tires on the back . I am new to this power level so any pointers would be great

How do you use the car? I have Toyo R888R's and I'm happy with them. It still spins, but it's a controlled spin. And I can make some runs through the canyons when I want.

They’re a bitch to find in a lot of sizes right now though

I don't have experience with Mickey Thompson ET STREETS but I have read nothing but good stuff from others (unless I am confusing them with another Mickey Thompson tire). Could you possibly be running too much PSI? I am only making ~600whp and running R888 (not their new R888Rs) and from a 40 mph, I am able to hook when I am at 25 PSI. I don't hook well at all when I have them at 32 PSI.

I keep forgetting that.

Didn’t even think to check the tire pressure … been out of the game for a while lol … I am thinking about the R888s 313/35 cause I had good luck with them in my last cobra but it was only a ported Eaton

Running R888 in 305/35/18. Perfect tire.


Edit:. I keep tire pressure at 28 psi.

Just pulls on the highway or back roads. Just hitting it in second the car spins like crazy … it’s somewhat controlled in second … third breaks traction but not too bad on the highway

Something must be wrong I make 740whp on my coyote car and those mt et streets dead hook from a 40 roll. 28psi cold, I would think the r888 would be marginally better. Either they're worn or the pressure is just to high.

They have about 50 miles on them … I’ll check the psi then … I plan on swapping wheels anyways just seeing what options are out there and if R888s are still a good option

Yeah my bet is too much air. But last I heard, you can't buy the R888s. You gotta go with their newer R888Rs, which I heard are better.

Another good option:

Hoosier 315/35-17 Drag Radial

Different car. Different suspensions. Different weight. Apples to oranges in this case.

I had an order for r888r since June through summit. Was supposed to ship on dec 20. FAIL. Second delay. Discount got the 275/35/18 fronts and 315/30/18 rears and they should be here by Wednesday. Little shorter sidewall but wanted the same brand for all 4. I have run nitto NT01 on both the cobra and my scca ranger and had wheel hop with both so trying the toyo this go around

These look promising I’ll keep them in mind thank you

What do you think they should be at ? 20 psi ?

Another vote for R888R. I have them on all four corners. Great tire.

start at 26 and go from there

How old are they/what’s the manufacture date on the sidewall?

I don’t think the coyotes hit as hard/same low end torque as the terminator either
