Leading evidence: 'Replace tire size' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, the most frequently mentioned possible cause is 'changing' (1 discussions; 0 report identifying it and 1 suggest it). The most frequently discussed action is 'Replace car has driven poorly' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

It seems the biggest problem was changing from 275 40 18's to 275 35 18's thought going back closer to stock was a good idea.
Outcome qualification: Negation, uncertainty or missing explicit repair resolution overrides the raw extraction signal.

Since tire change car has driven poorly to say the least.

I did replace Michelin ps2 with pilot super sports.

Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Hello all, had some alignment issues last summer. Changed the tire size on a "tuned" suspension. Since tire change car has driven poorly to say the least. Aligned twice with no improvement. I did replace Michelin ps2 with pilot super sports. It seems the biggest problem was changing from 275 40 18's to 275 35 18's thought going back closer to stock was a good idea. Only recently by dropping tire pressure from 38 f 42 r to 29 f and 32 r has the car driven closer to "normal" I'm a little concerned about driving at these pressures as they seem a little low, thoughts???
Thank you!.
What is the correct tire pressures for this car? What is the correct suspension for this car? What is the correct wheel alignment for this car under normal driving conditions? Questions answered. That's OIMHO.
Tire pressure for your car is 36f and 44r. I enjoyed the ride with the psi at 32f and 38r. Having the correct tire size is very important beyond ride comfort as the awd system needs the right height ratio in the tires.

At 36f and 44r my car has a tendency to dance a little at higher speeds therefore I've backed off to 32f and 36r and it settles right in. I have 235x40x18 on the front and 285x30x18 on the rear and they are Michelin Sport A/S.
Staying close to stock tire size is a good idea. OEM psi specs are for oem sizes. Dropping 10psi in each tire is a big difference & MPSS tires have a relatively soft sidewall so they seem to need 2-3 extra psi to feel right. I assume you dropped psi in steps not all at once. The issue is load capacity since it is the air pressure in the tire that supports the car so to answer your question you must find out the load capacity of your tire size with that air psi & see if it is adequate to support the weight of your car + occupants & etc. I assume you have the proper diameter F & R tires for AWD, but I believe you need to add psi, it's always better to have too much vs too little psi.
