Correct sizing on Weld Pro Stars I am about to pull the trigger on a set of 15" Weld Pro Stars and 275/60/15 M/T ET Streets. My question is what width should I go with? A 15x3 in the front? 15x4? 15x8 or 15x10 in the rear? I have 18x10.5's right now with a 56mm offset and I love the way they sit on the car. I was looking at the 15x8" prostars but they only have 3.5, 4.5, and 5.5" bs. So I guess this means this wheel will stick out a half inch further than my 18x10.5's? I am not against running a 325/50/15 but I'd like to have my 305's Nitto 555R DR's for the street and occasional track use, my ZR1's with 315/35 Mickey's for test and tune and the 275/60's with the prostars for bracket and shootout use. I do plan on selling the ZR1 wheels once I use the last couple passes the mickey's have on them, or put them on my S-10.
What do you guys think about the width and bs issues, and tire size?

I did a little poking around and found out the actual tire diameters for a 325/50 and there is no way I can fit a 28" tall tire. I have a 26.3" tire now with about an inch before I hit the fender lip. I am going to go with a 15x8" wheel out back with 275/50/15's a true 10.5" tire and 15x3.5's up front or 15x4's once I get some feedback on what everyone else runs up front. I just hope they clear the camaro discs. What bs should I run out back 3.5"?

15x10 & don't do it twice ... Tire wouldn't be a problem but 325/50 is too much ... A 295/ 40-50 would do great !! Do more research to what suits you best but I say 15x10 & 15x4 ... I'm in your shoes right now & going with the RTS wheels on my z28 ... Lowered 1" ... Running oewheels c6 z07 deep dish/rivets - 18x10.5 rears with a 295/45-18 nitto 555 tire. 28.4" with a lot of scrubbing but nothing the BFH mod can't do

Ok, I figured I would need to clearance the caliper to get them to fit. Grinder FTW!!! So, with a wheel that is 2.5" narrower than my 10.5" needs the same backspacing as my 10.5" wide wheels now? I thought if I wanted theses pro stars to sit the same way my 10.5" wide rear wheels do I'd need 2.5" less back spacing for them to do so since they are 2.5" narrower...can someone tell me why I'm wrong here?

I don't even think I can run a 275/60/15 without a lot of rubbing or a lot of modification to the rear fenders. I'd like to go ahead and train myself and the car to launch and hook on 275's because that is what the outlaw guys run, and every competition or shootout style event at my home track requires that you run a true 10.5" wide tire. I also think it would be more satisfying for myself to be able to say yea I dead hook on 275's with 600rwhp on a street car.

Well I would go with a 15x10 but if I want to run a 275/50/15 they don't reccomend a wheel wider than 9.5". The tire is only 10.5" wide, so a 10" wheel may not give it an optimal contact path upone launch which is why I am asking about the 8" and 10" wide wheel.

275/50/15s will be fine on 10" wheels. They actually work better on 10" wheels versus 8" wheels because of the shorter 26" diameter of them.

I am also thinking about this combo. I have a full set of zr1 wheels they are 17x11 in the rear. I have 315/35/17 mickey t et street 2's on them right now, but they only have 10 passes on them at best left. Should I run the ZR1's in the rear and a prostar up front in a narrow and short wheel and tire to reduce rolling resistance and let the wheels come up to help weight transfer? Or should I just go with prostars all the way around and sell the the zr1's? I was kinda thinking they would look good on my dd s-10...

Ok so now after seeing Camaro 396's thread with his weld rxt's I really want to just grit my teeth and bear it and buy them. One question I have is will a 17" or 18" alumastar or magnum front runner look weird or hideous with a prostar 15" rear wheel.
And how much grinding is needed to make the 15" wheels fit. I really want a plug and play set of wheels, but I don't mind at all making things work. I have a really nice dremel set that hardly ever get's used that I could put to work on the calipers if someone could tell me what where and how to go about it.

Well after reading that thread(thank you z28/2002) it sounds like I should just buy the wheels that fit without grinding. So will the 15" wheels fit in the back without grinding the caliper? I wonder how a RTS 17x4 front and Pro Star 15x10 rear looks like. Anyone got any pics of that exact set-up?
