The car is a 2000 AU2 XR8... Dealer fitted Noisy Crappy Directional tyres just before i bought the car... Once i got the car home i checked the tyre pressure...which was 45psi all round. Dropped it to 32psi all round and it drove a bit softer, but tyres started to wine..which is annoying..
7,000 kilo`s later i noticed both front tyres were wearing badly on the inner side of the tread.. With the car just clocking 38,000 Kilo`s i woundn`t think there was much suspension wear.. So i went to a suspension & Wheel Alignment shop and was told the alignment was perfect and the wear was due to crapy tyres and low pressure.. He told me to run 40 psi all round which i thought was too high?? With his personal car he runs 50 psi..which was a T3 with a XR front, super lows,18 inch rims running 245`s at the front and 265`s at the rear..450KW at the flywheel,Rotors were so large that he had to machine the inners of the rims to get them to clear.. Caliper`s were massive, No Plate had STABLE 1... The car looked pretty tough,colour was silver.. One Tough car! |

With lower profile and wider tyres you do normally run more pressure, in yours i'd run 38psi assuming they are 235/45/17's.

I have high pressures in mine, anywhere from 40 to 44.
Less than 40 and they squirm too much and wear uneven. Tyres are far better off with more pressure rather than less. They last longer, handle better, are quieter, protect the rims more, and provide better fuel economy. On the track I have run 50.

I run 40psi on the street in my 235/45/17's with no probs.
Off topic but why the heck would someone do this to a T3? Quote:

Even with my 205/65/15's I run 38-40psi. Just feels more confident on the road, anything less and it really accentuates the boaty suspension.

Once a tyre starts to wear on the inner/outer edge, it ussually will continue, are you sure the allignment is spot on, AU XR's are bad for inner tyre wearing, mine did the same, but the allingnment was out, only just though.
Have it checked by a reputable place. I run 38psi in mine. |
