I see a lot of people putting very wide oversize tires on the Fiero. I have also seen pictures posted of collapsed suspensions on Fieros. Are the suspension components built to handle the oversize tires or could they be causing the suspension failures? It seems as if the oversize tires would be generating an awful lot of strain on the ball joints and tie rods and control arms.

Many of the oversize tire/wheel combinations are lighter than the stock Fiero tires and wheels. The bigger problem is spacers, and they primarily wreck bearings. I think the suspension parts fail mostly because of age and neglect.

Depends on what you call oversize. Wider won't affect suspension other than to cause a harsher ride at times.

taller is another issue. It increases your final drive ratio and increases pressure on the tranny components.

Allot of guys including me do well with 55 series or 50's. I have 55x225 on the back and 55x195 on the front.

Okay, I imagine how hard the car is driven has an effect too.

Just running a lower profile tire will jar the bushings ans shocks/struts more due to there being less "give" to the tire itself. how to measure or quantify that I dont really know. I do know if your wheel offset is too far out from stock it can become harder to turn the steering wheel, which could be a sign that things are being stressed more.

I know there are some wheel offset/lowering suspension experts on this forum, they may chime in on this stuff too.

Todays cars that come with the very low profile tires have suspension systems that were designed for the tires. When the Fiero was built the low profile passenger tires didn't exist, so I would be concerned about the stress they would put on the suspension parts.
