345/30R20 Michelin PS4S Rear Tyres for R35 GT-R
Understanding the 345/30R20 rear size
A 345/30R20 is a very wide, low-profile 20-inch tyre. In this workshop package it was paired with a 20x12 +20 RAYS TE37 rear wheel. The photographed tyre was Michelin Pilot Sport 4 S.
Wide rear tyres demand careful clearance checks at the inner suspension area and outer guard, including under compression. Confirm the approved rim range, load and speed ratings and the exact product specification rather than choosing by size alone.
Wear can begin without obvious pulling
Rear toe can shorten tyre life without producing the steering pull a driver might notice at the front. Inspect the old tyres for inner-edge wear and compare left with right. Alignment cannot repair worn bushes, bent components or wheel damage, so mechanical condition must be addressed first. Pressure should follow vehicle and tyre requirements, not appearance.

Frequently asked questions
Is this package guaranteed for every R35 GT-R?
No. Year, suspension, brakes, ride height and modifications can change fitment. Check the individual car.
Can these staggered tyres be rotated front-to-rear?
No, because the front and rear sizes differ. Other rotation options depend on tyre direction and wheel configuration.
Why check alignment with new tyres?
Incorrect toe or other geometry issues can cause uneven wear and poor steering behaviour. Alignment cannot repair worn or damaged parts.
