Re: Windstar tire question
If you have the owners manual you can see how wide the rims are. You can phone a tire place and just get some advice on mounting 10mm wider tires on stock wheels. The tire size calc is good for verifying your speed with the larger tire size, just so you're aware of it. The height difference will be minimal at most (7mm) but that's not to say you could set the tire pressure at 30psi, instead of say 32-34psi and they'd be almost the same height as the stock size. Again, I doubt you'll have problems installing the slightly wider tires, but it's always best to check in with a tire shop.
