245/50 R18s instead of 235/50 R18s ?

[ppg677]

Hi, I'm driving a 2013 Genesis 3.8.

I run summer/winter tires and am tired of having to re-mount tires twice a year.

I have an opportunity for a decent deal on a set of 245/50 R18s. Pretty sure stock is 235/50 R18s.

Any idea if they will work? Tiny difference in speedometer/odometer?

Tire Size Calculator


245/50 R18 = .3" taller, .3" wider.

speedo offset = -.2 @ 20 mph up to -1 at 90 mph.

so on average you would read .25 to .50 mph slower.

Buy another set of rims.

I have OEM rims with summer tires and after market rims with winter tires. It takes 30 minutes at Costco (in April and November) to swap wheels instead of re-mounting and re-balancing tires on the same rims.

Yup, that's what I'm looking at doing-- buying an aftermarket set of rims.

I have the opportunity to purchase 4 245/50 R18 rims/tires for $600 (10k miles on the tires). Whereas speccing out a new set of tires/rims from tirerack.com is at least $1200.
