Hey guys, I'm looking at tirerack for some tires for my wife's '05 Hydunai sonata gls. My question is very simple: do I get new tires which match what the tirerack computer says I need (205/55R16) or one's that match what is on the vehicle now (215/60R16)? I think I go with the size which is on there now (??).

Thanks!

Did you put the 215 width tires on there? I'd go by the door sticker, some places won't mount the tire unless it matches exactly what is on the place card. Also if the tire is too wide (granted 10mm shouldn't matter) the wheel won't distribute the weight correctly anyways.

I'd go by the door, the used that size for a reason.

there are no stupid questions....
I once used a tire-sizing computer guide on the internet that worked well for me when looking at wheel offset, and getting a tire size that would clear my fenders & allow for a good fit when going to a new size tire than original. Lets see if I can find the link again.

Thanks, Polaris. The doorcard has 215 on it. I didn't even think to look. I need to start drinking coffee...

is probably more than you need. It is the best way to see what wheels & tires will fit right.
Of course OE is always about right for most vehicles.

Yep. Just go by the door sticker unless youíve got a good reason not to. I buy narrower snow tires, but I donít imagine thatís a consideration in beautiful SD.

I wish there was a way to "test drive" tires.

Going from tall & skinny 70R15's on my 2001 Windstar to wider (same height) 60R16's made a HUGE benefit to ride quality and handling!

I only like tall & skinny on 4WD trucks now.

That's a pretty standard up-size for better ride quality. Do they rub any? If they work and drive well, stay with the bigger tire. Most shops will put on what is on the car w/o hassle, as long as it does not show rub marks ...

Going from 215/60/16 to 205/55/16 would change your tire diameter over an inch and throw your speedo off by approx. 5%. On the other hand, my Focus came with 215/55/16 but 205/60/16 wouldn't change things enough to worry about.

Not a stupid question at all. Don't worry smile

I checked this site, and they seem to indicate that the correct size is 205/60-16. I also checked TR, and they also say 205/60-16 crzy

For the intended driving conditions, the best choice for you would be grand touring summer tires like the Goodyear EfficientGrip
