a stock MCS comes with 16x6.5 wheels. There's aftermarket wheels that are 16x7.5. stock tires are 195/55/16. Does it take a different size of tire to fit the wider wheel? Does wheel width affect overall diameter of the wheel/tire combo if the tire size stays the same?

yes for a 7.5 inch width you should go wtih 215s in my opinion. or even 205s, thoug the 205s will look a bit stretched.

 

Alex hooked me up with 205/50/16's Yokohama AVES 100s

I haven't yet found an on-line tire calculator that takes into consideration the wheel width. Does anyone here know of one that does?

For a good tire size calculator try
The Wheel and Tyre Bible - you'll find it about half way down the page.

 

Yeah I see the calculator, but it doesn't take into consideration wheel width. Is wheel width important in mounted tire diameter?

 

Not so much in diameter as in cross-section and tread width, I think... We used to purposely run wider tires (e.g. 33 x 12.50's BFG Muds on 8" rims) on narrower rims so that we could air them down really low for rockcrawling and retain the bead at very low pressures.

Not sure about how it works on street tires, but it works like a charm offroad! :smile:

Of course, you're running much higher PSI's for the street, and ours always performed fine on our Jeeps - as well as BFG Muds Swampers can perform on the street. Heh...

For the street, I think it's important to rely on the tire manufacturer's recommended rim widths for a particular tire.

That being said, I think I'll be running 215/45R16 Falken Azenis on my 'Daytona' 5-spokes quite soon, and while Falken recommends at least 7" rim width, many people are already running these tires on 16 x 6.5" rims with no problems.

 

I tend to seat with tire maufacture's recomedations for wheel wdth.
While narrow wheels, and low pressure are great for rock crawling, because they conform and mold to the terrain so well, and like to flatten out on the soft stuff.

The deflection a tire experinces when that low inflation pressures create addtional heat in the tires. Off road your speed with these excessivly low pressures tend to remain very low , under 20 mph. If these wewre run at low pressures at cosistant street speeds, 40 mph+, they would have more heat related failures. Works great in the sticky and rocky stuff though.

Please give us your driving impressions with your new Yokos, when you ge them. There are several of us who are contemplating getting the same thing.

 

Hopefully if the shipping works out correctly, I'll have them by tommorow evening. That way I can break them in on the fun-run to Tombstone on Saturday!

I'll give you a full report. What's nice is I'll have both sets and I can swap back and forth to get a really good feel for what they do.

After a while I'll end up selling those white 17" S Lites with the run-flats.
