Are your Michelin PS4S EV dedicated tires? Or just out of the shelf?no rubbing issues at all on any of the control arms. the 255/35/20 are basically a "stock" looking set up. I did a ton of research, and they are the sweet spot for these 9" rims. I really like the rims. The tires change the entire look of the car (for the better of course). make sure to set the tire set up in the wheel configurator to the track wheel designation as those rims have 245's as stock. This way the onboard computer system won't notice the difference in rotating circumference from to 26.8" to 27". And with tread wear, you will basically "wear-down tread rubber" into the range spec of the track package set up with the 245's. Highly recommend the Michelin PS4S.
64.1 center bore with +34 offset. There is another thread that covers this for the stock Uberturbine's but I am pretty sure this is accurate.
Where do you find these dB ratings? This is good stuff.Are your Michelin PS4S EV dedicated tires? Or just out of the shelf?
European Union obligates tyre manufacturers to disclose information on efficiency, marking them from A (most efficient) to G (worst), there are no D. Showing also noise of the tyre. Looking at available 255/35 r20 tires current availability is:
- Michelin PS 4S: efficiency = E, 71dB (Michelin PS4 is A-grade, but 30% more expensive)
- Bridgestone Turanza T005: B, 72dB
- Goodyear Eagle F1 Assymetric 3: C, 69dB
- Goodyear Eagle F1 Assymetric 5: B, 70dB
My first choice would be Michelin as yours. But here for EV I strongly consider Goodyear (assy 5) or Bridgestone. They could give better mileage than stock Pirelli, despite they are wider. There is a little risk: the fact your Michelin are ok does not mean Goodyear or Bridgestone would fit.
Could you share your efficiency you have now, on 255 with computer set to 245?
It’s on every european tire retailer webpage, or european manufacturers’ webpages. Keep in mind it’s not measuring how annoying tyre is, just measured dB needed by law.Where do you find these dB ratings? This is good stuff.
Yes that's probably consistent with Tire Rack being kind of a fitment Nazi. They did not want to sell me the Tesla spec 275 / 30 20 in Michelin Pilot Sport 4S Tire to put on a 10.5 inch rim because technically michelins listing does not allow 10.5 inch rims for that tire. I'm sure that's a mistake on Michelin part because the tire sits fine and is not stretched. Section width is wider than 10.5 in but I had a long argument with Tire Rack about this. They told me they would sell me the tire but if it failed that was on me. Did not endear me to tire rack.Just my opinion but I wouldn’t go 255. I just went 245 and they do add some rim protection. However they don’t look great on the 20s. I would not go past 245. Also check on fitment. Tire rack gave me a hard time asking for 245s and wanted to sell me 235s.
