Hey guys,

Been searching for hours now on the web and the forums, can't find an answer about wich tires to choose for a drag set up for my M6 SS, since the ET Street R Radial Tire P305/45R17 is not recommended for a manual... People seem to recommend bias ply tires on a manual but I can't seem to find one to fit in these sizes? Gonna switch them only to go to the track 15km from home.

Wich wheel should I choose then and what tires?

I've been running Nitto's NT555R on 20 inch wheels for a while but tired of this set up and the tires are pretty much done now, and best 60ft I could get was 1.8 secs....

Please help!

Interesting, I never heard the ET Street are not recommended.. Any reason why?

I'd like to know the details myself, but its what I found while doing my research; on the Summit Racing website you can read in the specs "Notes: Designed for automatic transmissions."

And in the Questions & Answers section you can read:

"I see these are recommended for automatic transmission. What happens is mounted on a car with Manual Trans?

A:
A radial isn't the best choice for a manual trans car in a drag race application. M/T now has a version of this tire in a bias ply which would be better for a clutch car. I would call them to discuss and confirm.

Alright found those but I don't understand the sizes available?

Is there one in there that fits on a race star 17 inch for my 2017 SS? Like the ET Street R Radial Tire P305/45R17

I wouldn't worry about it. It's more for clutch dumps where you would want the bias ply, (it wrinkles more and provides a little cussion to your clutch/drive train iirc) but then it's highly recommended you have all 4 tires bias ply. Don't mix them.

Our cars don't do well with clutch dumps. These need finesse to get off the line fast. My best launch is revving 3k and easing off the clutch. A little more aggressive than normal driving. Others say 4500-5k. I don't get to track mine often so they probably have a better idea than me. Just have to experiment with it.

Go to the street and strip bulletin section and click on #6. It will have some good info for bias if you go that route

Its a dilemma for M6 cars. DRs=good grip, but can cause breakage. Bias ply may need skinnies in front for good tracking. I'm considering Hoosier 28-10/17 slicks D06 compound and running them at a little higher pressure and see how car tracks.

Perhaps the other option is beefing up the drive train and running a DR (clutch, DS, axles, suspension). A tune break through that eliminates bog may also be needed.

[Solid_Sim]

Ok I see now... I never dump the clutch directly when launching, warming up my NT555R's good and releasing the clutch smoothly around 4-5k rpm gives me a good launch usually and its how I managed to make my 1.8 60ft...

I could go in 20inch DR's again but I'd like to try something lighter that grips more, just want to make sure I use the best tires possible for my M6 SS!

I don't think investing in skinnies would be worth it with my current mods also, so I think I'll let go the idea of going bias ply?

Ok so this wheel would be the best for a drag set up? https://racestarindustries.com/produ...ay-92-705253g/

With P305/45R17 ET Street R Radial Tire ?

[Solid_Sim]

Would this M/T Bias Ply fit on the Race Star 17x9.5 ?

http://www.mickeythompsontires.com/d...-street-r-bias

Also what will happen if I run the 1/4 mile on these and stock wheels/tires on front?

I don't want to beef up the drive train and run DR's like the normal ET Street R...

I want to get the best possible 60ft times without breaking anything!

[DFW1LE]

They should fit the 17x9.5 Racestars, however, those tires are 28.5" tall. I have heard that if there is too much difference vs front tire diameter, the ecu may not like it. What is the front tire diameter on your car? I have a 1LE, so it might be different.
