kumho Ecsta Spt

I'm Thinking of getting these for my 94 z/28. Kumho Ecsta SPT. 245/45-17 Front, 275/40-17 Rear. Any reviews on these tires? Is this tire size good for 17x9 ten spoke rims?
Thanks
Josh

I've had them for a couple yrs now.
245/40/18 275/35/18
Good looks Great wet and dry traction and a decent price IMO you can't go wrong.
If I were you I would stick with 275/40/17's all the way around esp. if you running a stock rim size. This way you can rotate the tires.
