Sumitomo Tires, my comments...

I bought some rear Sumitomos while back and have put almost 2000 miles on them. I just wanted to share with you guys how these tires are freaking great!!! They stick to the road like glue!!! You can''t beat the price at Tire Rack so if your in the need of tires try them out.

Hey guys, just traded in my 2014 Subaru BRZ and picked up an '11 P4S and I'm really excited about picking it up next week! Been doing some research on the wheels and I noticed a lot of people are going with the 22" setups and I have a few questions that I hope some people will be able to help me out with (I tried to search it first but couldn't find much on it)! 1) How do 22" wheels affect the air suspension system? Does it affect it at all? 2) Is the ride noticeably bumpier/rougher vs a 20" setup? 3) Is there a good recommended tire setup for the 20" and 22" respectively? If I remember correctly, AWD cars have to take rolling diameter into consideration. If I could get away with the 22" and still get a comfortable ride, have a working air suspension system (so that I could raise it over driveway entrances, speedbumps, etc)... I really do like the aggressive look of the 22" setup. I have a feeling I'll end up with a 20" setup though for practical reasons. FWIW, I live in Canada so this question is specifically towards a summer setup as I'll be running on smaller winter tires during the colder months.

Yeah, I have the Sumitomo HTR Z IIIs on my Evo and love them. They're what the 911 will get when the tires are done. They are just a touch noisy, but they stick well.

Hi, I have a Panamera Turbo with 22s on it and have zero issues with my air ride. I drive in sports plus mode with the suspension all the way down 99% of the time. My setup is 265 30 22 fronts and 315 25 22's rear. Keep in mind if you go with 22's and decide on 315's for the rear (which is the best look) it will be limit you on tire choices. BTW...I live in the suburbs outside the Detroit area and drove this past winter on the 22's with ZERO issues thru snow. This year I will probably buy a set of 20's for the winter and or a winter car....more so because I'm worried about other people hitting me then me hitting them. Congrats on your new car!

Thanks for sharing. I'll give them a try when my PS2's are gone. The price is just too good to ignore

There has been many threads about tire and wheel sizes, and I personally think you should do what you think works best (and in most cases looks best). I have been at the car mod thing a long (over 40 years) time and have lost count as to how many times I have pulled wheels and tires (I had three different sets of wheels and tires on the Gallardo I kept for two years) off all the cars I've owned. In the end I found that putting bigger wheels on a car always had a negative effect on its handling, though in the case of the Panamera I doubt most owners drive the car in a way that it would make that much of a difference since I also noticed the bigger and heavier the car was the less noticeable the change was. I am sure others here might even like the ride better and think it helps make it handle better. My most recent experience with a 650 coupe (I went from the 20" msport wheels with runflats to those wheels without runflats) that I ended up putting lightweight 19" wheels and Pole position tires, that change made me keep the car. I am a bit more picky about some aspects of a car than most people and mine is just an opinion. In the end you will be the judge of what works best for you. Congrats on your car enjoy it.

Now I know what Mannie Fresh was talking about in Still Fly. How expensive are they compared to Pirellis Contis or Toyos?

Welcome. Running 22s on my 4s when I had it and also on my turbo zero issues and run in sport or sport plus most of the tjme. Big wheel wells you will be glad u ran the 2s

I also switched to the HTRZ III's and have been very happy with them. Can't beat them for the price.

No one spoke of the air pressure they were using: In my pan 4 I reduced air pressure to 32 psi all around on Pirelli 255 20's and 295 20's and I had a noticeable better ride (read somewhere on this forum that 32 psi is ok as long as not going 160 mph). Ride was more like a luxury Jag/smooth. Here comes winter in Canada and I put on some 19 inch winters 255 and 285 Michelins at 33 and 35 psi (as -30 degrees here might reduce the pressure). Ooo La La what a beautiful ride compared to the 20 inch tires, even steering seemed smoother . In fact I seen a full set of 18 inchers and wonder what they would be like. Is the 20 inch scenario just a mental thing. What's your thoughts about a lower tire pressure being ok and the mental thing. EGL

They are way cheaper on tire rack compared to Perellis. Just check it out on tirerack

I've had lots of high horsepower performance cars. 20's are the absolute largest I would go and that's mainly due to the disproportionate effect that larger, heavier sets have on handling. Unsprung mass is a thing and changing it will completely change the way the car does just about everything. If you're just going for looks and you don't care about anything else, go with whatever size floats your boat. If you're going for the best compromise between performance and looks, and yes - it's always a compromise - 20's are the upper-end of what should be considered. Going up an inch equates to an (average) 10#-20# increase in rotational mass depending on the wheel and tire, and that is per-corner.

Thanks for the feedback. I am getting ready to order a set very soon, I've read some great comments from guys on Rennlist as well.

How is the tread life compare to Perellis? Anyone put 15k plus on these?

I only have about 2000 miles on mine, but they are wearing really well. No measureable tread depth loss, which is surprising. (Measured with a tread depth gauge)

Falken 452...they are great too.

Has anyone experience PSM getting way more "twitchy" with the Sumitomos? Just switched to them and my 2002 996 feels different (no big deal) and PSM seems to go off where/when it never did before (annoying...). Am I crazy? Or just driving badly?

Thread Resurrection! Anyway, just replaced the Sumitomo HTR ZIII's on my 996 Turbo after 22,000 miles. Fronts look like they will maybe go to 30,000. Great street tire.

I put a set of Sumitomo HTR ZIII's on my 997 last summer. They replaced my Bridgestone RE-11's. Terrible move on my part. They are fine for the street, but terrible on the track. They get much hotter than the bridgestones and have far less grip. I'll be going back to the RE-11 this year.

I tried a set of Sumitomo HTR Z III tires on my C4S. It was a mistake. I was pleased with the price of the tires, but they didn't handle as well as Michelins and they became very loud as they began to wear. I'm back to Michelin Pilot Sport PS2s and I'm happy.

65,000 miles... and I've only used PS2 since the start

I replaced the OEM Pzeros with Michelin Pilot Sport PS2 years ago and went through several sets. I'm about a year into the first experimental set of Michelin Pilot Super Sports and I prefer them to the PS2. Still lots of tread wear left and great grip and stopping in both wet and dry.
