Are your wheels forged, and what offset did you go with? any issues rubbing? I have fantasies that will never happen about cramming 18's over our brakes so I can run maxxis slicks @ 265/275 class width as dedicated track tires. Backup plan to run 19's or mayyyybe 20's to run Hoosier R7's. It'll all never happen.
My current setup is not forged, but I have another set that is "rotary forged". My current specs are 20x9 +35 with 265/35/20 all around.

Are they cheap or expensive?

Narrow is not the issue IMO. The prevailing advice that I strongly believe in is to concentrate on tire quality.

The issue is there is nothing that I can see that is stickier than Potenza RE71R's in 19's.

In 20's we can get a Hoosier R7 (for $500 each!!), but there are many more choices in the 265-275 class of tire. Especially 18's, if there is an available wheel.

Something definitely happens between 18 and 19 that makes tire prices jump. That's jump2. Jump1 happens between the transition from miata tires and regular sports cars :)

TW200 I think is the sweet spot for a tire that can be daily driven in a track tuned car. But there are really not many choices in that range. I would love to try a 180 but it's even harder to find a suitable 180 than it is a 200. Especially in a 235 or 245.

a series of disjointed thoughts on tires....

does that suggest that any of us can run a 9" wheel with a 35mm offset in 20 or 19 (or 18 if it clears the calipers) and won't have issues with 265 mm tires for track use?
That is correct. I used to run a 20x9" +20 and I had slight rubbing on the front when cornering hard, and going over bumps at speed. Switched to a +40 and then landed on +35 for my preferred look and no rub. I worked at Yokohama for 5 years, and recently switched to Gladiator/Xcomp. If you have any questions regarding tires, please feel free to message me. In my opinion, the fastest tire you can buy is the Advan A052 200TW. This is considered a cheater tire, as how fast this tire is. You can get about 1-2 track days out of it, depending on driving style. If you want longevity, go with the Michelin PS Cup 2's. Manageable to get 3 track days out of them. Toyo R888r's, melt up faster than any tire I have seen.

Couldn't find an 888 in the right size for me. they are a $450 class tire anyway.

Ever consider trying a <200 TW tire (besides 888)? are there any with a pricepoint low enough to get 1-2 track days out of like the advan but with lower cost of ownership assuming they are dedicated for the track?

Do the advans give you warning they are gonna go? I'm not convinced my RE71R's give warning at track speeds and forces. If really true, then there's no benefit over a true R-comp, I think.

Looks like advans are ~$340 which is "ok", but not sized right for our cars with OEM wheels. Size for our 19 is 245/35/19 which is 5.5% smaller. That means track-tire-only for sure, where as I can daily the RE71R because it's "only" 2.2% smaller. Price is also better at about $260 a tire.

I guess if I had 20" wheels I could run the advan 245/35/20 at $320 a pop which is "better", and only 1.8% smaller than OEM, so it's daily-able on top of trackable.

------------

Longevity is not a care of mine, more like price per mile. If the tire is $150 a pop it could melt off in 9 months and it's still cheaper than most of the options considered. at $260 a pop for RE71r's I pay (tire cost alone) $1560 "roughly" every 30 months-ish, and it covers light tracking and 12,000/yr miles of daily use, while letting me use OEM wheels.

It seems every other option costs more, either with $2500 in new wheel costs or by going to a $500/ea class of tire that won't last as long.

The gladiator is the first tire I've seen that might be equal to the RE71R at the lower pricepoint. That means it could reach end of life way earlier and be totally OK. at $160 a pop and $1560 every 30 months, I could change them at roughly 6 month intervals on the front and 1 year intervals on the back and still be equal money in.

THAT is what has my attention.

I would love for you to try the Gladiator Xcomp HP at the price point that you found. Please give me some feedback and I will gladly send you some swag.

I got 19's, can't do it. Also my tires are new from October, so I won't need new front's 'till Christmas and new rears 'till summer 2023. Unless I get better on track and destroy 'em quicker :)

Otherwise I would put those on a short list for sure!

Did you have to do anything else to get those wheels and tire to fit without any issues? That’s my next upgrade and want the widest, stickiest tires.

I have zero issues and did not make any suspension adjustments when I first had them on. Zero rubbing. I did rub when I had a 20x9 +20mm 265/35/20. But when I switched to the same wheel in a +40 offset, the rubbing vanished. Clears brakes and fender linings, yet is almost flush. I have since updated to the KW V3's.

Jim, the # of track boogers at Laguna is nuts. Your tire is coated there :)

It's MUCH better at other tracks, at least for me!

By the way, for anyone that wants it, the 200TW cheater tire is back, and online reviews say it is every bit as good as the original.


I for one will re-up to these, for sure.
Never thought I would leave the track with more rubber on the tires that I arrived with, I just hope that rubber is stickier than what I had already!
