tire size and ride smoothness

[marshallcs]

What is the relationship between tire size and the smoothness of the ride.

From what I've read, I understand that the low profile tires give you a harsher ride then a car with a much higher profile.

So therefore, if I wanted to have a more comfortable ride (and was willing to do the Tech2 changes needed for a 2002 3.5) would a tire with a higher then stock profile offer me a smoother ride?


Thanks guys.

I don't believe there is a direct relationship on size tire versus ride quality. It has alot more to do with how the tire is constructed. Low profile tires tend to have a stiffer side wall in order to add strength to the tire and that may harshen up the ride quality but I have friends that run very low profile tires that handle and ride super. To tall a tire could also give you a poor ride.

Changing tire size, especially tire diameter, is not usually recommended when you have ABS and onboard computer controlled type suspensions and drivetrains.

Personally I believe it comes down to tire design and quality construction. The most expensive tires are not always the best.

Tire pressure can also impact a tires handling ability and ride.

Thanks a bunch. What would you reccommend to smooth out my ride even more? I remember the feel of an old caddy--- where you couldn't even tell you were moving other then seeing stuff outside go by. I don't need it to that degree, but a bit closer would be nice.

For a smoother ride in an all-season tire, try Goodyear Assurance ComforTread. I'm not very perceptive as to a car's ride characteristics, but even I noticed the improvement right away over the previous Bridgestone Turanza LS-T.

That will definately be my next car purchase. Thank you

Another great tire that handles super with no noise is the Yokohama Avid V4s. I run them on my 95 and I know that other members also run them with super results.

Should be able to find them for under a 100 bucks a copy.

all i can say is comparing the ride comfort on sidewall heights of 16" vs 17" rims - tire's outer diameter being same - 17" were disappointingly rougher for me. I like it more last couple days when having my winter tires on original 16" rims.
So, IF you have goodlooking 22" aftermarket rims, you could consider on UPgrading to factory OEM 16" ones. ;D

I dunno, I've had the opposite effect so far. My 255/45/18 BF Goodrich G-force KDW's so far have given a much more positive driving experience then the 235/60/16 Goodyear Integrity's I replaced then with. I'll stick my neck out and say just going down the road they're smoother, they don't bounce and squirm over every little perfection. They hit small-to medium much more solidly (in a good way). They get the bumps done and over with as opposed to the 16"s which have a 'rocking' effect to them. Large bumps and big potholes are rougher, there's just no getting around less/a much stiffer sidewall and much higher PSI (48 cold vs. 35 cold). Though, that's a trade-off I'd make anyday

It seems as if there isn't any definitive answer to this question. Is there anything i can do/change/add to soften and smooth the ride? suspention changes?

Thanks guy--- I'm glad this thread was atleast a little interesting.

Sidewall height does affect ride as well as the stiffness of the sidewall in a tire. No doubt. Goodyear's are known for having cushy sidewalls. Check them out at a Sam's club or other store where you have access to the tires. Or, if you have a reputable tire dealer, ask him. They surely would love to sell you what you desire in a tire.
