How big of Tires can I have?

I have a stock height 93 s-10 blazer and was wondering how big of tires can fit? My buddy wants to sell me a brand new set of Wild Country tires on rims. They are 295/10.5-15's. Will these fit my truck? Please let me now. Thanks!

Biggest tire that will fit on stock suspension is 30x9.5x15. I run these on my Blazer with no rub or clearance issues. I think 295s are too wide.

Thank you airforceone for the info. Now I can go get accurate prices on tires.
