I am looking to get some all season tires for the stock 20" wheels since I am also getting a dedicated set of tires for summer and track days. I would like to get some non run flats for less weight, lower cost, and a softer ride.

High performance all seasons in the right size range for 20s seem to be pretty limited. The best I have found is the Toyo Proxes 4, but the sizes are either too tall or too short.

My preferred setup since it would raise ride height a little bit:
255/45/20 Diameter: 29.1
275/40/20 Diameter: 28.7

Lower ride height:
245/40/20 Diameter: 27.6
275/35/20 Diameter: 27.5

Will a tire that is 1" taller than stock fit? Any other recommendations for high performance all seasons aside from the SP Sport 7010 A/S?

For the GTR the best all season tire for the stock wheels is the Dunlop SP Sport 71010 but it costs alot.

If you go with non runflats have a plan for any flat tire. AAA or other road service is good with liberal allowance for tow range.

The GTR is super high performance so no All Season tire less than Ultra High Performance is worth considering- get the best but all season is the place to start in my opinion.

The Toyo Proxes 4 is a good street tire but not for the power of the GTR.

If you need help try Alex@tirerack.com extention 294 and tell him Brad from Hawaii sent you.

You want a tire diameter as close to stock as possible 28". Too tall will decrease tire to wheel well clearance and raise ride height and road clearance- higher center of gravity would be opposite than what you want for a performance car- handling and cornering at speed would be worse. Another reason to get really good sticky tires- consider how much you drive in drier but cool weather vs rain or light snow. Each tire may do slightly better in any of those conditions.

Note that you need TPMS in your wheelset then go to dealership to sync them with the GTR if you own more than one set of wheels for summer vs winter driving on the street. Track wheels do not need TPMS.

Some good choices-  for Ultra High Perf All Season tires. Note you can use the same tire size for front and rear if it fits the rim width ok, and you get the same tire diameter front and rear at the same time.

Another choice is-

Pirelli PZero Nero All Season
275/35-20 $272 each, 400 treadwear, 32 lbs, 102 load rating XL

Talk to alex about the slight differences. As long as you don't expect track like handling you will be fine with any of these tires for street use in three seasons. The Continental gives up a little on handling but gives long tread life and has a good price. The Bridgestone is overall the best for performance but has higher price and slightly noisier ride with faster tread wear. Pirelli also good on performance.

Thanks for the recommendations. I spent some more time researching your suggestions, but I ended up going with the Toyo Proxes 4. I have 245/45/20 and 275/40/20 which are .7 inches taller than the stock tires. They were less than $180 per tire after shipping. I am really happy with them compared to the RE070Rs. They are quiet, ride more comfortably, and the car drives like a normal car on the freeway instead of wanting to pull different directions. The little bit of extra ride height makes it easier to clear speed bumps and sloped driveways, which even at stock ride height has been a problem for me a few times.

As for handling and traction, I am happy with both in the dry and in the wet these seem to perform better. I have a set of dedicated race tires for the track, otherwise I would have gotten something like the Michelin Pilot Super Sports instead.
