Haha, not really, because what can he do now? Slicks? Brick under the gas pedal?

I saw a ton of MT out there which is not surprising. I didn't have any confidence these tires would work at the strip this year. Tried 16# to 25# but nothing helped.

Yes sir, you are past the point where multi-purpose tires are going to work for max straight line performance. At least you can take comfort in knowing you tried.

R888R is not a drag strip tire, period. Great rolling racing and high HP street car tire, but that’s it. At the drag strip, time to break out the drag pack my friend.

I've got a set of 17x10 bead locks and I dusted them off when I got back home. Someone said the MT ETS R is now hard to find. I think I need the P315/50R17

For 17” drag wheels, you want 305/45/17.

Why would I choose the 305 rather than the 315? A 17x10 wheel fits both.

305/45 is a 28” tall tire that will fit your wheel well and should play nice with your front runner tire (need to be within 1” of each other). The 315 is a 50 aspect tire that is 29.4” tall…probably going to be a problem on both fronts.

My fronts are 26.65 in. and Mickey is 28.1. Close enough.

Front and rear needs to be under 1" difference or stabilitrak freaks out. So I wouldn't do the 315/50.

Either way, not much you can do as hard as that blower is spinning to get traction. I could pull timing out of it down low but I still don't think it does enough.

You might consider a smooth boost controller so you can lower boost on the hit.

I've ordered the 305. BTW, the OEM rears are 1.1" taller than fronts which is about what the 305 will be.

Shoot me a tune with an adjustment on the hit. I'll do a T&T soon with Mickeys and send you the logs. Thanks.

My times:
60 ft. = 1.85 (ran 1.58 last year)
1/4 = 10.35
mph = 145
