Up front, I know nothing about cars. I recently bought a 2017 Encore with 18" wheels. Question - could 17" wheels work just as well? Any problems with that change? Performance? Ride? Here is my, "this may be a stupid question" - what would be the difference in the vertical heighth of the two sizes (wheel+tire)? Another way to ask is, how much would it lower the frame of the car? Her's my problem - I have mobility problems and it is difficult for me to lift my leg and put it into the car with the 18" wheels. Even 1" would help, but is that all I could expect to gain by changing sizes? And again, can you change sizes without problems? Thanks.
Hi,Jerry,Yes,you can use 17'' rims.And if you use 17'' rims,The wheel bolt pattern should be 5*105,wheel offset should be 39mm.If you use 17'' rims,There are not too much difference from 18'',from 17'' to 18'',that very close.The vertical height is not wheel+tire size,just wheel size.How much would it lower the frame of a car?you can put both 17'' and 18'' tire size into tire calculator,It can show you the difference of diameter.For your mobility problem,Can you explain it?You want to use 18'' wheels in your car?Why you need to chang size?
Thanks, John, for the reply. I was trying to keep my post short and didn't explain myself well enough. I've had hips and knees replaced and have limited mobility when lifting either leg. If changing to 17" wheels lowered the car an inch or two, it sure would make it a lot easier for me to get into the driver's seat. Yes, I can turn and sit first and scoot in backwards, but that requires me to open the door wider; in tight spaces that is not always possible. I don't want to do anything that would alter the performance or ride of the car, though. Almost all of my driving will be short trips around town. Also, I have read that the speedometer may not read properly if certain(?) changes are made. I don't know what you mean by using a tire calculator. Thanks again for your help and advice.
