i currently have 195/50-15's that are 40mm wider in the front and 20mm wider in the back, no rubbing problem in 6+ years. i just ordered 185/60-15's to replace them, i'll get those installed this friday, i know a person who has 185/60-15's in the front and has no problem.Thank you. I wish I could try tires on like I do shoes. Do your tires rub when making tight turns?
before i drove it, i turned the wheels to "full lock" and could still fit my fingers between the tire and the front wheel well, so i have about 1/2 inch clearance, only drive slowly at "full lock". the tires are quiet as well, when on the highway with the old tires i had to play my radio at volume "14" (smart model 10, 6 CD changer) just to hear it, now i can listen at volume "11", now i can hear wind noise and the blower motor that is starting to go out again :laugh:Those new tires really fill the wheel wells nicely. Looks good!!
i got them on saturday, in 185/60R15's very pleased with them. yesterday we got 6 inches of snow and my car handled like it had snow tires or that there wasn't several inches of snow on the ground, no wheel spin or slippage! (my ABS/ESP has been AWOL for 5+ years). along with being quieter and smoother, should have got these instead of the lousy Kumho's in the first place, just to save maybe $50-60!
The best size for a smooth ride is a 155/65R15 front tyre fitted to a 3.5" rim and a 165/60R15 rear tyre fitted to a 4" rim. Continental make matching winter tyres in both these sizes. You can run the latest Continental winter tyres all year round, as long as you don't overheat them in the summer by driving too fast.Hello,
I have a 2012 Passion and looking to buy 4 new tires. I currently have 165/15 front and 185/15 rear. What is the best size for a smoother ride? I am looking to stay with 15 inch rims.
I do not recommend fitting narrower than stock wheels onto a 451. For what gains you get in comfort, you can make handling and emergency maneuvers into a mess.For the smoothest ride you need to fit any given tyre size to the narrowest allowable rim. Also make sure the tyres don't have rim protectors built into the sidewalls as these will make the ride harder. Rim protectors are extra thick rubber moulded into the sidewalls. These make the sidewalls stiff and hence give a harder ride.
The sidewalls bulge out when fitting a tyre to the narrowest allowable rim. This protects the wheel from kerbing damage far better than extra rubber moulded into the sidewalls....if one happens to use car washes that have tracks, forgoing wheel protectors will lead to mangled wheels after your first wash. I know that from experience.
185/60R15 tyres have a 603mm outside diameter. The standard 175/55R15 rear tyres have a 573.5mm outside diameter. By fitting 185/60R15 rear tyres instead of 175/55R15 rear tyres, you are raising your gearing by over 5%. This is a very big change and as well as reducing your car's top gear acceleration and possibly making your speedometer underread, it raises the car's center of gravity by almost 15mm.Honestly, a vastly better option is 185/60/15 on all corners. You get improved handling, improved highway performance, better treadwear, a happy ESP system, and they're significantly better than the stock sizes at soaking bumps.
It seems our differences may be more geographical?The sidewalls bulge out when fitting a tyre to the narrowest allowable rim. This protects the wheel from kerbing damage far better than extra rubber moulded into the sidewalls.

A disadvantage to running the same size tyres front and back is that the car is relying on the car's electronics to prevent it loosing the back end in wet and slippery conditions especially in emergency and sudden accident avoidance maneuvers. The ForTwo is a very short wheelbase car, and you need to consider the handling characteristics on the limit. One unfortunate ForTwo owner fitted the same size tyres all round and during an emergency maneuver in wet and slippery conditions lost his back end. The car hit a brick wall and was a write off.
In dry conditions there are no such problems, as the car's front suspension camber causes the front end to break away first ie. understeer. Understeer in the ForTwo is safe, oversteer is not.
