View Full Version : "Plus" Tire & Wheel Sizes for RWD 1995 Fleetwoods

01-09-07, 07:06 PM
I ran across this plus tire size tire/wheel chart for my 95 FWB for those wanting to go with aftermarket wheels of larger diameter. Staying within these tire sizes limits when going to larger wheels should keep you about the same overall diameter and not impact speedometer accuracy too much to help you avoid clearance problems.

Plus Zero

Your speedo will still be off with most of those sizes.

You really need 255/55/17 for example to keep the same diameter as stock.

I had to get my PCM reprogrammed to compensate for my new tire size..

Thanks for the correction. I imagine trying to find the exact plus size tires that wouldn't affect speedometer accuracy at least a little may be nearly impossible. I'm wondering now who I can find in Jacksonville area that could reprogram my PCM.

Are those the 18"s on the FW in the post? That looks like a good proportionate wheel size for a Fleetwood and mine's a Triple Black as well. I'm trying to decide which wheel size I want. I didn't want too get too large or too low profile.... I don't like that "Wagon Wheel" or "Bicycle Wheel" look you sometimes see. I think its looks particularly bad on a Big Cadillac.

Yes, those are 18 inch 2 piece forged Enkei SST-2 wheels on my car. They are wrapped in 255/45/18 Michelin Pilot A/S tires. I had a gentleman in Fort Lauderdale from Diablo Motorsports reprogram my PCM for the tires and my modifications when I lived in Miami.


Before I had 17 inch Chrome Impala SS wheels with custom Cadillac centercaps with BFG 255/50/17 tires.


I think 18 inch wheels are the perfect fit for these big cars and still provide a large enough sidewall to maintain comfort and security.
