i had a set on my protege years ago and loved them. i cant seem to find them anymore. also what is the best tire site these days? without edge racing, i just dont know what to do

 

Kumho XS, and is a WAY better tire than the MX.

www.vulcantire.com (besides the obvious tirerack.com), www.1010tires.com, www.td4l.com

 

XS. Just tested them and was very impressed.

 

do they handel heat like the mx's did? i seem to remember they would heat up and they would grip wonderfully. 615's are probably what ill go with, but people tell me the 615s get really sloppy when they get hot. i know my old rs2's would.

 

615s, like most aggressive street tires, do grease when they get too hot or overinflated. The 200 tread rating is very aggressive, also - mine lasted less than 10k, but they have wonderful grip. I hear the XS is better.

 

i just found mx's on tire rack! maybe ill try a 245/40/18 and 275/40/18 . would i need any kind of spacer in the rear with that wide of a tire?

 

What are your wheels sizes and offsets? I run 275/40/18 with a 10.5 +15 rim and it clears.

 

my stock 18 wheels on my 2007. its probably a bit of a strech but the wider the better

 

had the MX tires on my Z. HORRIBLE is the only word to describe them. Under PERFECT conditions they were decent - 80+ degrees, new clean blacktop, no moisture. If conditions aren't perfect they don't grip. They lasted about 15K miles

edit:
Friend had them on his MSP and they were great. Not the right tire for the Z
