Should I Replace My 255 Series Tires.....

[ozarkmark]

Ok. So I got a steal on a 98' 528i a few months ago. The only thing that is not right with the car is the size of the tires. The people that owned it before put 255 60R 15's on it when it should have 225's!!!!! Boy do they fill up the wheel well nice.

They also handle extremely well. Cornering grip is enormous and they do not scrub!! Lucky me.

Should I be concerned enough about this to go out and buy a new set that is the right size?

The only negative I have experienced is the suspension seems to wallop a little bit if going over semi rough pavement. It seems to me this is a result of incresed unsprung weight.

ANY ADVICE??

Thanks.

HELLO????? Does anyone have any input?????!!!!!!!!

nope

you like em? keep em, as long as the tire fits and it handles well i don't see why not? the only problem that i can think of off the top of my head is that your speedometer will be messed up but that's about it.
i mean people put huuge chrome wheels on their 5ers that they got in a local hip hop accessory store and their cars are fine

the increased unsprung weight is ridiculously minimal in comparison to rim changes, BBKs, etc which is all common stuff, so they shouldnt cause a problem. Perhaps you have suspension problems. The only problem I see is the speedo being incorrect since the ratio seems to be improper.

if the car calls for 225/60/16, they should be more like 255/45/16 (I may be wrong, check the book) to keep speedo accuracy.

255/60 is like a 4x4 tire, no wonder it fills the wells nicely.

Thanks for the input fellas. To my utter suprprise, the speedo seems to be tracking 60 second miles at 60 MPH.

Those automatic radar guns the highway patrol sets-up before construction zones seem to clocking me accuratley as well.

I was just curious if this was a huge issue.

Other than the speedo (which seems to be a non issue for you) its not a problem at all if it don't rub

i agree with sp0rky
