my scion tc came with 215/45zr17 tires. will i be able to fit 225/45zr17 tires on the stock wheels? i have the opportunity to get a good deal on a pair of good tires
The 10mm wider is only about 3/8 inch total really, and should not be a problem at all. Going one size up or down doesn't make a difference unless you have lowered the car or something like that.
First of all they will fit just fine,- no difference in readings on speedometer! You do not get into speedometer problems till you change circumference of tires! -- All you are doing is putting on a tire that is 10mm wider - this is approximately 3/8 of an inch. Barely perceptible! If using the same wheels. this comes in with different series tires, (#s in middle of specs). For instance if there was also a 55 series tire, the rubber between road and rim would be greater, - making the circumference greater also. A forty series would be less, making circumference less also! There might be a very slight advantage in putting wider ones on back, -should marginally affect handling characteristics, -- but then again it may not even be perceptible, --- if you aren't doing competition driving! Wider tires might give you just a wee better control of break-away of traction in very tight high speed turns! Since the wider rubber has just slightly longer adhesion before skidding (or spinning car out)!
The 225 tire will have a diameter of 25 inches vs 24.6 inches for the 215 tire. Your speedometer will be 1.4% slower than your actual speed When it reads 60 MPH you will be going 60. MPH These tires will work. You want to be sure that you have the same size tires on each axle (Front and rear)
