235/45 or 245/45 (17's)
Guys,
Between these two profiles, if you wanted to have a bit more "comfort" would you choose the wider or skinnier of the two?
I currently have 235/45's and though they're great, i'm still out of spec (speedo) and i'd really like to cushion the ride a bit more. I'm hoping the 245/45's will help a bit.
I've read that wider tires transmit more road feel but also soak up larger bumps better. Skinnier tires, though less road feel (i guess in a way, comfort) it doesn't do as well with larger bumps.
Thoughts?
Thanks.
(p.s. they'll be going on 7.5 or 8" wide wheels, so no issues there)

These specs are based on the Avon M550 A/S which are going to be my next set of tires. Read the reviews on Tire Rack.
Stock 215/55/16 revs/mile = 821
Plus 1 235/45/17 revs/mile = 818
That doesn't throw the speedo off much at all, almost unnoticable. Going up to 245/45/17, which I'm thinking of doing also, puts you at 808 Revs/mile. Thats about a 1.6% lower speedo error, which isn't bad at all. It's less then 1mph at 60.
45% of 235 = 105.75mm tire height
45% of 245 = 110.25mm tire height
While being minimum, just about 5mm, I think the larger tire might fill out the wheel wells a bit more. And I do agree that ride comfort should go up ever so slightly because of the additional profile.
More tire = more cushion.

Thanks for the response
Actually, my numbers are just slightly different (2k2 Max) since the OEM's were 225/50's but the consensus is the 245/45's will be a much better match to the OEM's than 235/45. I'm just hoping the added width does add to some noticeable level of comfort.

Hoping someone can help. I'm looking to get a set of Falken Ziex 912's for a 2001 Maxima SE, with OEM 17" rims. Looking at the Falken site, the OEM spec 225/50R17 have 805 rpm's, and fit 6"-8" wheels. I see that 245/45VR17 tires also have 805 rpm's , and fit a 7.5"-9" wheel. Since the rpm's are the same my speedo would still be accurate, but here's a stupid question since this is my father-in-law's car. What size are the OEM wheels, as I've seen them quoted as 7" and 7.5". And will the extra 2cm cause any fitment issues?
Thanks for any help.
