i got a stock 99 4x4 blazer, and as it sits now it has 215/70/15 with no lift. i'm thinking about replacing the tires i would like to keep the rims tho. but i would like to go with more aggressive looking tires cause they just look at bit to small for it if ya know what i mean. what would be the best size to make it look good with out the lift and even later on when i get around to setting it up with a lift. thanks

 

30x9.50-15's or the metric equivelant...

 

and those will fit on the rims i have already

 

Yep... you can install up to a 31x10.50-15 on your stock wheels.

 

will they sit right in the wheel wells without a lift?

 

From what I've seen from other members yes it would just fill up the majority of your wheel well. look at bandidolenny's signature it should give you an idea as he is running 31" tires.

 

30x9.50x15 or 245-75-15 which is right about 29.5 tall and 9.6 wide.

 

my front wheel well is 30 1/2" and my rear wheel well is 32" across so i need a tire the will fit in place of a 215/75r/15 with stock suspension. without rubbing

 

most blazers come stock with 235/75/15. mine measured about 29.5" when I had 235's. funny thing is they are maybe 1/2" shorter than my 31's
