240zBoy Posted September 1, 2009 Share Posted September 1, 2009 I have a street v8 build in process and just love the look of 15 inch rims on the 240z's without a fender flare. The problem is that the tire size is 225-50 so I wanted you guys to let me know if that will be able to hold 280-300hp? I have heard that I need to go to 16 but without flares I just think the 15's with that tire size look so much sexier. In my eyes I think it will be plenty tire for that amount of power and especially if a decent quality tire is bought. I am not going to go to the drags and this is a street car but I still want to be able to have the option of launching from a start to prove the v8 to all my honda boys. Well lets see what everyone else thinks cause I don't wanna make a mistake here cause thats $$$ Quote Link to comment Share on other sites More sharing options...
jnjdragracing Posted September 1, 2009 Share Posted September 1, 2009 If it is the stock suspension is should hook up pretty good. We are still amazed at how well our Z hooks up and launches. John Quote Link to comment Share on other sites More sharing options...
240zBoy Posted September 1, 2009 Author Share Posted September 1, 2009 So with a max of 300hp if the 15 is acceptable then that would be awesome. The RB 15x8's I am going for with 5mm spacers. Keep the opinions coming. Quote Link to comment Share on other sites More sharing options...
DREW RBZ Posted September 1, 2009 Share Posted September 1, 2009 Consider going with a drag radial. I switched to the Nitto 555R drag radials and they hook very well. Quote Link to comment Share on other sites More sharing options...
240zBoy Posted September 1, 2009 Author Share Posted September 1, 2009 Alright:mrgreen:, The only dissadvantage to the rims is the wheel pattern of 4x100 but then again every one is in that boat unless you got in on the group buy for 16's or something. Correct me if I am wrong but is modern motorsports the only place to sell adaptors cause they are pricey:shock: Quote Link to comment Share on other sites More sharing options...
johnc Posted September 1, 2009 Share Posted September 1, 2009 Traction has more to do with tire compound then tire width. A 225 width drag radial will have more traction then a 335 width Sears Roadhandler whitewall. Quote Link to comment Share on other sites More sharing options...
Drax240z Posted September 1, 2009 Share Posted September 1, 2009 (edited) With that said, the Sears Roadhandler whitewall would look very nice. I ran 205/50R15's on my car for 2+ years, street and autocross, with modified suspension and an LSD. The HP and torque output was in the same neighborhood as most street V8 swaps. The tires were Yokohama A032's (No longer available) in the soft compound. I found they were excellent for street use, and I'd happily run a similar DOT approved race slick on the street again. Keep the compound soft, especially if it's a low mileage car. Less than 10,000km a year, I wouldn't run anything else. You'll be just fine with 225's and a nice soft DOT legal race compound tire.

240zBoy Posted September 2, 2009 Author Share Posted September 2, 2009 Thanks Bartman that was just what I needed. I knew more then one place had them and there $35 less. Quote Link to comment Share on other sites More sharing options...
Drax240z Posted September 2, 2009 Share Posted September 2, 2009 (edited) You can't go wrong with either TTT or MM products in my experience, I run items from both in my car and they are both top notch to deal with. Looking at tires, for $125ea (225/50R15) at tire rack right now, I'd be looking at the Michelin Pilot Sport Cup... Yokohama Advan A048's would be another good choice. Wish the Yokohama A032's were still around, they weren't a super-duper autocross tire, but they were good in wet weather and a nice INEXPENSIVE high performance street tire...

janaka Posted September 2, 2009 Share Posted September 2, 2009 225's would be good enough for street driving IMO. I have 245/45/16's out back (yes they rub on big dips in the road) but if I ever get the fenders rolled they should clear. My drag radials are only 235/60/15's and they hook decently well for a street legal tire. As said above compound over width, I'm down grading the 245's to 225 R compound when my tires are done as I have a set of Hankook Z211's or some odd name like that in the basement. WAY stickier than the Sumitomo's I have now (200 rating). Quote Link to comment Share on other sites More sharing options...
