My compact Vibe has 205/55R16 tires H rated. I want to put 215/60 or 65 16 on at T rated. Is this a crime against humanity. And yes I know it will affect my speedo a bit, but it will improve ride, mileage, and I can buy cheaper tires.

The Vibe really can't do 120mph by the way.

You can put anytire that will fit under your car on your car. You will just want to make sure that when you turn the wheels that the tire doesnt rub on anything.

most vehicles can use a larger tire, ie the 205 is smaller than the 215 the second number ie 55 vs 60 is the tread depth and the lower the number the deeper the tread. the r is just the rim size. putting a larger tire on a vehicle increases milage only slightly for each higher size, the deeper tread gives a better milage rating for the tire and does give a smoother ride. when you have the tires inflated, have them use the full pressure rating or 2-3 pounds higher. it will keep the sidewalls from breaking down as easily. some vehicle makers say that for the best ride, set the pressure to what they recommend, however the difference in ride versus the tire damage due to lower pressure is significantly more important. the ride is nearly unnoticable, but the damage from lower pressure will ruin a tire faster. most tires are rated for 32 psi (passenger cars) but using 35psi gives a longer sidewall life for the tires. also, keep the pressure checked at least once a month. a tire guage costs about $2 but is easy and accurate for 99% of all needs. you'll get longer life and better milage with the right pressure.

Well the change in speed on the speedometer will be about 5.3% so when it reads 60mph you'll actually be going 63mph. This will also affect your odometer. Here's how you read a tire size: The first number is the width of the tire in millimeters. The second number is the aspect ratio (not the tread depth), and is a percentage of the width. The aspect ratio, divided by 100, times the width of the tire, gives you the depth of the sidewall. R stands for Radial, and 16 is the width of the wheel. Maybe you could have the speedometer re-calibrated for the tires, but you may increase the rolling resistance and unsprung weight which would be detrimental to handling and fuel mileage. I don't see why you would want to get cheap about tires though. You only replace them every few years, and they're the only safety feature that actually touches the road.

keep the narrower tires. the only reason you would like to have wider tires is because you have a traction problem. the smaller tires will drive better but just get them taller. the less mileage warrenty (ie. 25,000 miles) the less tire and the less it weighs.. you would get better milage too. just talk to the tire people and they should help you.

Tire size affects the speedometer/ odometer and transmission shift points.amoung other things.
