wheel/tire fit questions.....

[Ross]

I recently obtained an 06 buick lucerne 60,000 miles with oem
17x7 chrome wheels with 235/55-17 tires. The car came from a salt state and the rims are highly corroded and have a history of air leakes. I am going to have to replace the wheels at some point. There is also corrosion in the valve stem area,

Question. I found a set of new gm buick lacrosse oem rims on e-bay for a good price. They are painted aluminum and not chrome. They have the same bolt pattern but are 17x6.5 (not the 17x7 currently on the car).

1. Can I use these 6.5 inch width on my car with the 235/55/-17 tires?

2. Will there be any issues with the TMPS going to the 6.5 inch width?

3. Any drivebility issue with the more narrow rim?

Thanks for any input you can give me.

1) I would check tirerack or your tire's Manufacturer site. They will specify which range of wheel widths are safe to use.

2) don't know

3) Nope. Unless of course the manufacturer of your tire recommends 7inch or wider rimes. Usually OEMs don't takeit to the edge of recommended widths. So you should be fine.

yes, no, no

the recommended rim width is 6.5 to 8.5

The current chrome rims were an optional tire and wheel combo offered by Buick.

The rims on eBay were likely were part of a standard tire and wheel combo.

Why not have the current wheels inspected by a tire shop that you trust? They may be able to clean the beads to the point where they won't leak, and may be able to use an aftermarket stem to fix the problem there.

They may have to dismount one of your tires to check the bead on the rim (so they can see how bad it really is), but they'll be able to put the tire back on in the same position so it won't have to be rebalanced.

I'm sure that your set of rims isn't the first set that a good tire shop has seen in that condition. It may be easier than buying a new set of rims.

Those rims shouldn't be in that kind of shape at 3-4 years old, even when exposed to salt. When I see or hear of a odd problem like this, it makes me wonder if the previous owner may have not been much interested in proper maintenance.

the beads usually don't leak. if the tires are slowly losing air and there's no hole in em, then your wheels are probably cracked. and there's nothing you can do about that except replace em all.

also if it's a reputable tire shop, whenever they dismount a tire they should always remove the weights on the outside of the wheel or the weights will slide around and scratch up your wheel when removing the tire.
