original stick is 235 and that is the orinal size from the factory also they are the original wheels also
im not tryign to cheap out or anytihng i just wish it was not so hard to find 2 tires to match the ones i have a pair of 225-60-16 in the basment that came off of my old lincoln they only have 2k miles on them they cost me like 100 each and i can get another 2 for 89 each after shipping
other wise im going to spend like 450 or 500 on 4 new tires again
only tires i like are michalen symmetrys or kumo solus
only tires i really trust for some reason
so just trying to see if the 225 will be ok or if not also
Looks like the 225's are about 1/2" less in diameter that the 235's, so you'll lose 1/4" of height - not enough to worry about. Your speedometer will read a tad high: when it says 60 you'll really be doing about 58.5.
Otherwise, it's just a slightly smaller tire, so you'll have no problems.
also will i be throwing anyting like the MPG off will i loose and go down to a lower MPG or is that not going to happen
and also with the tire being smaller i know like if i fill my tires with 45 psi air
it makes the ride stiffer then if i put 35 and 40
will the lower tire my make ride stiffer ?
or will it just make it more responsive
You'll probably never notice a gas mileage change. No need to carry high psi - run them at 32 psi, cold, and don't bleed any air if you check them hot: the pressure will be a bit higher, hot, and that is normal and built into the tire specs. I also doubt that you'll notice any ride change, BUT you are going to be running a slightly smaller tire load-wise, so treadwear may be somewhat more than predicted by the UHTQ rating.
I've got 225's on my STS and they have been fine. You can physically tell the tire is a bit smaller, but it's not too bad. The ride quality is pretty damn good (we're talking cheap Tiger Paw Uniroyal's here), but with the smaller size the handling takes a hit. Took my car (which had 235 Michelin Symmetry's before) from a good handling sedan to a true marshmellow - were talking Deville here.
If you're aren't worried about handling I'll say go for the 225's. If you still enjoy taking your car around bends - spend the extra $$$ for the 235's.
I guess handling really isn't as much as an issue here as cost is. I'm going back to 235's next time. Symmetry is a good tire, but I want something a little more sporty. The Pilot MXV4 is looking good right about now, but a little pricey.
Go to www.coopertire.com and get to their CS4-V all-season H-tire. I've been running them for 2 years now and am pleased. Great in the rain. They have a long treadwear life and come with a "Try 'em for 45 days. If you don't like 'em, we'll take 'em back."
