Bruce Nunnally Posted May 26, 2006 Report Share Posted May 26, 2006 Welcome. The 97 STS is a fun car; similar to the 96 STS I had prior to my CTS's. The stock wheels are 16"x7", or 7" = 177.8 mm wide. So the 225mm tires already are somewhat wider than the wheels. http://www.1010tires.com/ has a tire width comparison tool that does the math for you. I compared a 225/60-16, a 235/55-16, and a 245/50-16 tire. This resulted in an overall diameter of 26.6 inches (stock), 26.2 inches (235/55) and 25.6 inches (245/50). Interestingly, the site suggested that 7" wheels are the minimum width that you would want to use with 245 mm tires, so that may be your answer on what is the widest you can fit to the wheel. I am not sure what the widest tire I have heard reported as a good fit on the Seville. Often people are moving up to the 17" wheels or higher. Cardio Doc carries a lot of caddy take-off wheels on ebay; email him you got his info on Caddyinfo and maybe he can set you up with a deal.

Bruce Nunnally Posted May 26, 2006 Report Share Posted May 26, 2006 Which tires is a favorite debate topic, but I think the Michelin Pilots are great if you have the cash. If, like me, you probably are going to burn the rubber off anyway through corners and leaving it on the pavement, less expensive tires are preferrable. Another thing to consider is sometimes you can get wheel/tire combo's on ebay for less than new tires, then resell the wheels.

Bruce Nunnally Posted May 26, 2006 Report Share Posted May 26, 2006 OH -- Mark 99 STS is running some 255/50-16's on his 99 STS, Michelin Pilot XGTZ4'S, (when he is not running slicks). They will be a bit taller than stock, but that may help the look even if it means the speedo is off a bit. Mhenchley is using some 245/45/18's on his 97 Deville, so apparently the 245's don't rub either.

woody Posted May 26, 2006 Report Share Posted May 26, 2006 Kurb, Welcome. I also live in Michigan and have a 97 STS. These guys on this forum are the best. There is nothing that can't be answered. Woody Link to comment Share on other sites More sharing options...
Fast95SLS Posted May 31, 2006 Report Share Posted May 31, 2006 Welcome aboard, I think that you will find this site enjoyable. I have used 255/50-16 on my 95 Seville without any problem. I use BF Goodrich Traction TA on my car with good results. I have bought them at Sears for $110 a tire. They are a V rated tire. Link to comment Share on other sites More sharing options...
kurb Posted May 31, 2006 Author Report Share Posted May 31, 2006 im on a budget i was looking at some falken tires here: http://cgi.ebay.com/ebaymotors/255-50-ZR-1...069167217QQrdZ1 i know they arent rated high or anything but i dont plan on going extremely fast, ill only need them to last me this summer because ill be getting rims afterwards, and i cant see any tire as being worse than what im rolling with now. these are pretty cheap i can get the whole set for 370 shipped to me what do you guys think about this in my situation Link to comment Share on other sites More sharing options...
JasonA Posted May 31, 2006 Report Share Posted May 31, 2006 Those Falken tires were rated pretty well by Consumer Reports a few years back, but a lot of people on the CR tire forums report problems with air leaks and imbalancing. Many have had tires replaced due to defects. If your current tires are relatively new, or at least have good tread, and you plan to get new rims/tires later, I don't see the value added in buying a set of tires in the interim. Save your cash for a quality tire (another happy Michelin Pilot user here) when the time comes later this year. Jason(2001 STS, White Diamond) "When you turn your car on...does it return the favor?"

scottshoe Posted May 31, 2006 Report Share Posted May 31, 2006 I live in Michigan, and I have a 1997 STS also. I have 255-55-16 Kumho tires on it. They are the same diameter as stock, so the speedo is accurate... and they only rub in reverse when near full lock. The car looks awesome with these tires on it, and they weren't a lot of money. They are a tiny bit noisy on the E-way, but your stereo should fix that problem! They are awesome in the rain and suprisingly not bad in the snow. I got them at Discount Tire, after getting a price from The Tire Rack for them to price match. If you go on "craigslist" and search "1997 STS" my car should come up and there are a coupe of pictures with the tires on it. Link to comment Share on other sites More sharing options...
