What size hoosier QTP slick for CLK 16" Wheel?
Everything I can find says 255/50/16 hoosier QTPs, but all the hoosier sizing is done differently.
I THINK the only one that will fit the 7" CLK wheels are the 17431QTPRO here: https://www.summitracing.com/parts/hoo-17431/overview/ Those are 26 x 9.50-16 . I don't have a clue how those measurements work but Summit brings them up as the only tire that will fit on a 16x7 rim. Is that the right one? Thanks guys. |
Okay so after obsessing over this for a while, I found that for some reason summit just isn't labeling them quick time pro, just calling them DOT slicks.
http://www.ebay.com/itm/Hoosier-DOT-...VXXCW1&vxp=mtr But on the summit PDF I found the part number on they recomend min wheel width of 8". I just want to make sure that people actually use the 255/50-16 on the 16x7 CLK rim and I wont have anything messed up. I was going to grab 15mm offsets as well. Thanks guys! |
You want the DOT Drag Radial, not to be confused with the Quick Time Pro DOT. I think the QTPs are bias ply.
To add to the confusion, the DOT Drag Radial recently underwent a design change, so it is also called the "DR2". I just got a set of the DR2s and they are fantastic! https://www.tirerack.com/tires/tires...rtnum=55R6DDR2 |

You sure? Every one seems to swear by the QTPs? Also, the part I can't find any where on the forum, what size?!?! For the 16x7 rim haha. Is 255/50/16 okay even though the rim is an inch thinner than the Hoosier recommended rim size?
And yes, the 255/50-16 will work just fine on the 7" CLK rim. |

I can't speak to the QTPs, but I can tell you I've already run the DOT Drag Radials on the CLK wheels for three seasons. I just replaced my original set with a new pair of the DR2's and I have no reason to look elsewhere. The setup is incredibly light and I have no wheelspin problems, even on an unprepped track. I get 1.6x 60' times consistently.

Oh and while I've got some one thats actually ran them, is this the correct wheel style?
http://www.ebay.com/itm/Mercedes-Ben...%257Ciid%253A1 From what I can find in the search it needs to be the W208 wheel and I believe that's it, just want to make sure it is before I buy it and then it doesn't fit over the caliper haha. |

No, those are the crappy cast wheels. Not sure if they will work or not. The good ones are these forged factory wheels:

I am also set on getting the DR2 tire as well.

Those are great 60" times. What kind of tire pressure are you running? 20PSI cold? or even lower?
I just got the new DR2's and only have a few runs on them, but they seem stickier than the old ones. Maybe just because they're new, but next time out I'm going to see how high I can have the pressure while still dead-hooking. I'll have results on the 9th. :zoom: |
