Clunking

Im getting a clunking noise from the front suspension when hitting small bumps up, nomally at slow speed up to 50mph. Also my front tyres have about 5mm of tread in the cente with about 1.6mm on the edges but the inner side of the drivers tyre is worn right down to the thread and the outer side of the passinger side tyre worn bald. Any ideas what the problem may be? Its a 92 V6 with standard suspension.

Well the clunking could be a number of things, but it sounds to me like you have a Strut or Strut mount problem. As for the tires wearing our like that, it may be your camber/caster is out of wack and you may want to get a alignment. How many k's does your car have?

Tire wear is two things. One you need an alignment and two you are running to little air pressure in the tires (32 PSI cold air pressure in the front and 34 in the rear). The clunking is usually from a strut going out, a bad sway bar end link or bad outer tie rod.

Car has 100,000 miles or 160,000km. Ive been running tires on 32psi cold front and back on 205/40/17 and check the pressure every 2 weeks.

Since you are running in lower profile tires that stock the factory infation values don't necessarily apply. Toyo for example is recommending in the 35-37psi range less pressure in rear the their product manual given to the dealers. I was running 40psi front and 36 rear with a set of 215-40-17 T1-S and got nearly 52000km on them. Other company tech books have similar recomendations for inflations with low profile performance tires.
