245-50-15... i know dunlop has a size... but i need more opions... does any other manufacturer have this size??

doh...I posted a reply before my brain even completely registered all the info!
I looked on tirerack.com for 245/50/14s and came up w/ BF Goodrich Radial T/As for $98 a piece

..then I realised you were looking for a 15" wheel size, LOL
...going back to tirerack.com again...

*edit*
I only found competiton Hoosiers for that size tire, $185 a piece

nope, dunlop sp8000s is it. I have a pair. If you go with 15s, just stick with 225/50s for the street, awesome selection in that size. The dunlops are too much money for what they are. You can get better grip from some of the sticker tires in 225s then what the dunlops offer (though they're not bad) and for alot less. You can get some hoosiers in that size as well, thats about it.

I've been doing a bunch of research on tires for a project that I'm working on now. Your best bet for the 15" rims are going to be the 225/50R15. There is a large selection of tires at this size. On the downside your going to be reading slightly slower on your speedo. (63MPH when your speedo shows 65MPH)
