I posted this over at the Vortex and thought I might as well post it here, too.
I'm just looking for the best tire I can put on the factory alloys. My question re the Firehawks is based on the following specs from tirerack:
Tire/Rim Range/Meas. Rim/Tread/Diameter
OEM Contis-------5.5-7.5/5.5/8.2/25.0
OEM Goodyears--5.5-7.0/6.0/7.9/25.0
OEM Michelins----5.5-7.5/6.0/8.0/24.9
Firehawks----6.0-8.0/6.5/7.0/25.6 I also confirmed the Firestone specs at their website.
A 6" rim is within the rim range for the Firehawk and is only 1/2" narrower than the measured rim.
I'm not worried about the diameter (revolutions per mile will be within 2% of stock) or the tire potruding from the rim as long as the tires will be safe and perform to specifications on my rims . . .
I found the following online (from the Tire and Rim Association):
"The TRA also has developed a measuring rim for each tire size that enables all manufacturers to measure their tires on the same size wheel. For 50-series tires and higher, the measuring rim width is 70% of the tire's section width rounded off to the nearest 0.5."" (In this case 9 x 70% = 6.3 rounded to 6.5).
"Choosing a wheel near the middle of the range will give a balance between ride quality and handling. A wider wheel will improve handling at the expense of ride quality, while a narrower wheel will improve ride quality at the expense of handling. Consider these compromises when selecting wheels." (In this case choosing the narrowest wheel in the range would maximize ride quality at the expense of handling).
Anyone running 225/60s on 6" rims?
