Guest zfan Posted January 23, 2006 Share Posted January 23, 2006 Well I am looking at new tires and maybe rims but found a pair of Konig rims I had forgotten about. They are 16X7 and the tires I really want are 255/50-16 M/T drag radials. M/T recommends an 8" rim, funny thing is BFG drag radials that are 255/50-16 recommend using a 7-9" rim. Would it be unwise to go with the 7" rim? Why would one say yes and the other no? Mike Quote Link to comment Share on other sites More sharing options...
jap tin Posted January 23, 2006 Share Posted January 23, 2006 The 7 inch rim will be fine.The narrower rim will alow the tire to grow more on the top end than a wider rim. Quote Link to comment Share on other sites More sharing options...

Mikelly Posted January 25, 2006 Share Posted January 25, 2006 YOiu might want to get someone at M/T on the phone and discuss this. I once had a very enlightening discussion with someone from BFG about shoe-horning a set of tires onto rims about 1 inch narrower than recommended. You might be ok for normal driving, but the additional forced put on the tire diring hard launches could potentially cause you to have sidewall deflection issues and problems with the bead holding. Last thing you want is to have a tire de-bead itself on you at about the 300Ft. Mark when you're well into the power band and speeds are UP! Is it probably? Maybe not. Is it possible? Talk to a M/T tech to get that answer. Mike Quote Link to comment Share on other sites More sharing options...
Scottie-GNZ Posted January 25, 2006 Share Posted January 25, 2006 I would not. The general rule of thumb is the wheel width should not be less than 70% of the tire tread width. That combo is exactly 70%. The reason I so no is because I have the same tire on Z32 NA wheels that are 16x7.5 and I can see evidence that I am not putting all the tread down under hard acceleration. You can play with tire pressure to compensate a little. Jap-tin's point about growth does not apply as DRs do not grow at high speed.

Guest zfan Posted January 25, 2006 Share Posted January 25, 2006 Thanks Guys! I do not want ot take the risk of losing a tire at the 330 ft., 1/8th mile or what ever. Might ruin a perfectly good pair of underwear! Mike Quote Link to comment Share on other sites More sharing options...
