FYI: From a google search, I assume that the lower resistance # equates to a faster wearing tire ? If the vehicle equipped with standard Original Equipment, low rolling resistance passenger tires normally provided 25 mpg in the city and 30 mpg on the highway, installing tires with 20% greater rolling resistance would only drop fuel mileage by a calculated 3% (to 24.25 mpg) in the city and a calculated 5% (to 28.5 mpg) on the highway. While this is a measurable difference, it probably isn't much more of an influence on real world fuel economy than being stuck in rush hour traffic a couple of times a week or being stopped at every red light instead of continuing through a string of green lights. The easiest way to reduce rolling resistance to enhance fuel economy is to make certain that the tires are properly inflated. A vehicle that requires its tires to be inflated to 35 psi (based on the vehicle's tire placard) will have an increase in rolling resistance of approximately 12.5% if the tires are allowed to become underinflated to just 28 psi. Therefore, maintaining the vehicle manufacturer's pressure recommended for light load and heavy load conditions may almost be as important as the tires being used.

Indeed the difference in rolling resistance vs fuel burn is low , unless the coach is driven a bit. I'm not sure with most bus campers going 5000 a year the difference in the sales tax between the poor tires and "best" can be recovered. However competition for your tire bucks may make it possible to get a good set of numbers at almost Zero over crappy numbers. The Yokohama RY617 102 is what I find as cheap to fit and not bad compared to some. WE are still months from a test ride on the transplant , so the rolling diameter is still up in the air. "Knowledge is Power" ,so digging out the tire list , for after the tire size is finalized , was the task , so I shared my finding , for those interested. A 5% difference could be expected (worst to best)at lower speeds (under 55mph) with less at higher speeds where aerodynamics rules. FF | ||

This is proof that tires a much more then big black round donuts that hold air and support the bus. With our low mileage per year, I'd be more interested in traction for handling and braking then a low rolling resistant tire for fuel mileage. Better traction can make the difference between hitting and not hitting. Good Luck, TomC | ||

Tom, I agree with you 100%. My classic car's tire inflation spec's calll for 18-22 lbs. in the front tires, the tire Mfg's number on the sidewall says 32-35. At the higher pressure the car's turning ability is severely hampered, it understeers (goes straight when I turn), floats like a boat at freeway speeds and it takes a LOT longer to STOP because the front will lock-up & skid. People who make the tires have no idea of the dynamics of the particular vehicles the tires will be mated to so they use a general rule of thumb so to speak. When rolling resistance gains priority over safety you can bet that trouble will not be far down the road. ......skinny solid rubber tires have the least rolling resistance of any and I don't see many running them on their rigs! | ||

Rolling resistance is definitely on the list of things to consider, but for me, it is not the most important, but it will be used to choose between the applicable tires that made the short list. For my driving history, a high traction tire will save more than higher rolling efficiency. . . . . | ||

The truckers that actually drive the tread off their tires do not seem to have problems with either traction or wear. 175,000 seems common on the Michelins as steer or rears. AS we remove tires at 8 years , it is seldom there even half gone. Sure in my old Porche Speedster years the soft high traction , "wischen" on the corners days , the rears only lasted 13,000 , but it was a great!!! fun 13,000. There was also some trucker concern about single wide rear tires and handeling in the rain and snow , but experience has shown no problems. Theoretical contemplation on "trade offs" is fun , but go to a trucking board (usually 100,000 -200,000 miles a year)to find a operators opinion. FF | ||

Tire composition is getting better all the time. I see it mostly in the motorcycle tires I buy. It used to be that you either had a high mileage tire or a good traction tire. Now because they have started to bond multiple composition rubber into one tire you can have the higher mileage rubber in the center where most of the wear occurs and the better grip on the outer edges where you need the grip around corners. . | ||

Jack - You gonna put a 140 in the 'Brier? W/ or w/o 4 carbs? Better search for an Otto Parts oil pan & valve covers to help cool that beast! NO scoops on the sides, tho - that's a high pressure area & scoops block the air flow. Wish I'd known you're working on a motor, recently got rid of a 164 turbo block that had the freeze plug for the FC/Lakewood oil filler. . . Seriously, date code S/N was correct for a turbo, but it had the casting/plug. Parts supply at this end is excessive, eBay is assisting in reduction. To bring this back to the topic of tires, GR78x14 (P215/75R14) radials mounted on 6" wheels off Chevelle station wagons w/ drum brakes, works very nicely on an FC w/o having to cut up the rear wheel wells. FWIW & HTH. . . | ||

4 carbs RJ....with the orig. air cleaner cans! It's the 2nd one I've done. Always use the deep oil pans and the BIG filter w/ the 90 deg. adaptor & a spin on plate...elect. fuel pump is SOP too. Check your E-mailbox for some pics! (Message edited by Jack_fids on July 13, 2010) |
