Looks like tirerack has them on the website for 305/30’s on the 20in rims. Just curious if anyone has them and if so, any track times?

They say they are not for street even though they are DOT approved.

???SORRY no news. Maybe some of the other drag racers will give feedback. I know what its like to struggle for the right wheels and TIRE. it can be overwhelming with all the different options and materials. I saw a carbonfiber wheel; if that gives you any idea..

Yeah. I am pretty sure that I am set for my regular wheel/tire combo...on the street, I will run the R888R’s 315/30’a or I might run the MT Street 305/35’s. Either option will require me to relocate my wiring harness. Ok. So that’s done.

The R7 says it’s not intended for street use. But the size would be a perfect replacement for my current rears. If it was good enough, I might just order another set of rears with these Hoosiers and just have a different track tire on 20’s...but still have the R888R’s which will be good enough on the street.

I love the TOYO r888r tires. They have a lot of road noise. By far the loudest tire i have ever had on the street. but they hook like nobody's business. If i could do it over i would only order 2 for the rear; save money and buy a hankook envo. i think was the name on tire rack website but they are cheap a compared to the others. If you like turning left and right then TOYO on all four corners.

You're asking about using R7s for mixed drag and street use I'm assuming? I'm speaking strictly from my armchair as I've never personally run any of these tires, but here's my 2¢ based on what I've heard/seen elsewhere.

For drag: R7 is probably not the tire you're looking for. They're designed for road course use and need to be pushed for a lap or two before they get grippy. Hoosier says you want to measure temps in the pit at 180-200°F, meaning you'll need a little higher than that on the track. I might be wrong, but that seems to be a bit higher than you can heat the tires thoroughly with a burnout. An A7 (if you can find them in that size) would be the better compound for temperatures because it only requires 110-140°. On top of all that, both the A7 and R7 have pretty stiff sidewalls, but if you're sticking with the 20" rim you might not be able to get around that one

For street: I wouldn't run an R7 on the street if I didn't have to. Sure it's got DOT certification so it's technically legal, but it's gonna wear the tire out very quickly and you won't be properly heat-cycling it from street driving. Because of that, you might have even less grip later in the tire's life even if you do get it properly up to temp. If you manage to get them hot on the street, you'll start throwing rocks and other road debris everywhere as well if that makes any difference to you. You're also probably gonna have a bad time if you get caught in the rain with them.

Thanks for the feedback. Makes sense. I like the idea of the R888R on back. I would probably just stick with G2’s on front.

That does mean that I am probably back to getting a dedicated 17in setup for the drag strip.
