335/30/18 R888R vs 345/35/18 R7
My street tires **** the bed on my last autocross. For giggles I looked at what a set of Toyo R888R run in 20’s and 18’s. It was $1750 ish shipped for a set of 19/20’s and only $1190 for the same tire in a 18”. As I’ve been dying to run my CCW’s on the street, and I want to compare them to R7’s on the track, I decided to buy a set of triple 8’s in 18”. I’m going to run the triple 8 on May 10 at Thunderhill, then put the R7’s back on for May 11 to get a back to back comparison to see what I like playing on more.

Triple 8 is a good looking tire. Mounted Comparison.

The R7’s have a **** ton more grip lol. My brand new R888R put in within half a second of 4 day old used R7’s, in the same 285/335 size. The R7 in 315/345 are way better. The 285/335 R7 had slight understeer characteristics while the 315/345 had slight oversteer characteristics and are my preference hands down. The 285/335 R7 are easier to push at the limit as expected with understeer.
R888R is a great tire, and very consistent and easy to slide with my set up. Very good street/track combo. But I will be sticking with R7’s.

^^^^^
Are thosepics with the r888r on a 18x12 or 18x13? I have a square 18x12 setup and want to know if that 335 r888r would fit well on that width wheel.

From an engineer’s standpoint I don’t see how the R888R could be close to the R7 in grip. The amount of contact patch is so greatly reduced by the huge channel and large angular tread voids. I’ve read many times that they wear extremely well. The voids probably provide plenty of room for heat to dissipate from the rubber, but at the expense of contact area.
As a relatively new guy in this game I’ve just started to run R7s. I find them about equal to Cup 2s in the same sizes. I expect the 315/345 combo should be better tan the Cup 2s due to its extra surface contact, will be running them next.

The Trofeo R’s I considered, but after I looked at enough reviews, they are such a compromise in the wet you may as well have Hoosiers.
