For those of you worried about squeezing the most mileage out of your tires,here's a trick that has helped me in the off-road world,I.E.much larger tires on 4x4 trucks and jeeps. What I do is take a piece of white chaulk(any vibrant color will do though) and draw a line rt to lt across the tire tread.then I fuel,load said vehicle as I would when I am using it for the intended purpose,then I drive said vehicle up or down my driveway about 10 to 15 feet(enough to give the tires one or two complete rotations)and check to see how the chaulk line has rubbed-off.If it has rubbed-off in the center of the tire there is too much air,if it has rubbed-off on the outside edges,there is not enough air in them. With alittle experimentation with the air hose you could be runnig straight across the tread pattern, For our 14 RT LIM. it seems to be 24lbs. in the front and 32lbs. in the rear(I noticed with the recomended press. in the front, the tires looked like they were "rolling-under" on the sides from cornering). I hope this helps some of you folks out there in spyder land. Be safe and ride on!!:spyder:
