Hi all, I have purchased a new Aurion AT-X last week with additional rear parking sensors and 17" alloy wheels, all from Toyota dealer. Due to the lack of knowledge in car mechanics, I have trolled Toyota Owners Club forum quite regularly. Infact, I have been reading the Aurion manual. On this New Tyres topic, Toyota have given me 235/45 ZR17 97W. What issues will I be facing when I need tyre(s) replacement? As the normal Tyre Specification sticker indicates 215/60 R16 95V and 215/55R R17 93V only. Also the recommended PSI per tyre is 30 as listed on the sticker, however what is the correct PSI for my tyres? Did I made a bad choice for upgrading the wheels? Jools.
