Has anybody here put 18 inch wheels on their 87 to 91 Bonneville?
If so what tire size do you run?
I was down at a local tire/rim shop and the guy brought out a 245/45 - 18 and it looked like it might fit.
The overall diameter looked about the same as my 225/60 16'* but they were a little wider.
Just wondering if there was any problem rubbing.
Also please post some pics of your 18'* if you have 'em.
Thanx, CD

I would be interested in anyones experience in this to, considering I'm going to do it hopefully next month, it'd be nice to hear if anyone had any major problems to watch out for.

a 245/45/18 is the biggest sze you can fit without problems, at least thats what is for the newer gen bonnies. If i had 18'* that is the size I would buy. If your still not sure, then try a 235/50/18 or something.

just make sure the overall diameter is close. I say go with 245s. 18s would look sweet on these cars, ive seen pics of these cars with 18s.
EDIT: welcome to the club! you drive a sweet car

Did a little research, looks like they should fit fine.
..........................Width........Sidewall height........Overall height.........Circumference
225/60 R 16......8.86" ...........5.31" .....................26.63" .....................83.66"
245/45 R 18 ......9.65" ..........4.34"..................... 26.68" ....................83.82"
difference......... +0.79" ........ -0.97"...................... +0.05".................. +0.16"
Actual Speed....Indicated Speed...........Speedometer Error
65 mph ............64.88 mph ....................... -0.12 mph
100 mph ...........99.81 mph ........................ -0.19 mph
If speedometer has been calibrated for 225/60 R 16 tires, replacing them with 245/45 R 18'* would result in the speedometer reading low by 0.19%.
Same as with the speedometer, if odometer has been calibrated for 225/60 R 16 tires, replacing them with 245/45 R 18'* would result in the odometer reading low by 0.19%.

Doug, I'm interested in your stock wheels if you get new ones. Also, I've got a white SSE bumper I'll trade for an LE, preferably silver, charcoal, or black in that order of preference.
