Hello all. I put my OEM (22”) summer rims / tires over the weekend and inflated them to 45 lbs all around as per the door jam sticker. It rides OK but what pressures are others running and if different pressure front to rear, how do the sensors set to measure that? I can’t find the screen to set the baseline pressures when I looked for that screen on Saturday.

thank you.

35 psi all around.
there's a setting for "light load" somewhere in the software. rides much better at 35 psi.

I thought all U.S. (or North American?) SVRs came with Pirelli all-season tires. Was this an option in your model year (to specify summer tires)?

I believe they started offering the summer tire option with the '21 MY refresh. it seems like most dealers still spec the all seasons, and it's probably the default. I had to specifically option the summers when I ordered my '21 MY.

Very cool, thanks for confirming! How do you like the summer rubber compared with the Pirelli all-seasons? Big difference, or hardly noticeable? Is the treadwear considerably worse?

BTW, to keep this post on-topic, I also run the 35 PSI all around for "light load." Anything over 40 seems to negatively affect the ride quality and harshness over bumps, driveway apron lips, grates, etc.

haven't done a direct comparison but I presume the summer rubber makes a pretty decent difference in terms of handling and feel. the p zeros are jaguar specific so there's some actual development that went into the tires specific to the vehicle. haven't noticed excessive wear so far. definitely a true summer soft compound though, as the tires pick up a lot of grit and make a lot of noise in the wheel wells with any loose gravel etc.

I run scorpion winters which actually do a pretty good job in the colder months, but the summers are definitely more communicative/less mushy feeling. my guess is the scorpion all seasons would be somewhere in between.
