    Default Tire pressure Spyder newbie dumb question......

    I have a 2014 RT and the manual says 20 for the front and 28 for the back tire. Coming from almost 40 years riding motorcycles, most folks including myself would find a sweet spot higher than what the manual would say. Would love to have real world experience for the 2014 RT tires. They are stock. Thanks in advance.

    Recommend using the BRP specs on the tires. To soft gives a soft and squirrely ride. More than 28 in the rear will expand the tire and make it wear out prematurely in the center of the tread.

    Yep, riding a Harley for the past 20 years, I wasn't buying the specs. Figured it was a typo, but they're on the money.

    I have a 2014 RT-S and i run 18 in the front (my preference) 28 in the rear. Most important is that you have both front tires at the same pressure, 1/2 lb off will affect your ride.

    find your sweet spot and stay with it.

    Start out with 30 in the rear and 22-23 in front....ride a few miles until tires heat up....see how it goes. Let out 2# in rear (don't go below 28 in rear) and front and repeat...like Joe says...find your sweet spot. On my 2011, riding solo, 30 rear, 18 in front and that's just me.

    Default Tough one..!!

    considering your ryding style, weight, double or single ryder makes for a wide range of recommondations. Always recommend you start with their suggested pressure and adjust it to suit you. JT's Machine Shop (sponsor on the home page) has a dual filler for the front tires that keeps them equal...good luck..!!

    Jt's Machine shop is a vendor on here and sells a neat little device that you connect to both front tires and fill from a common fitting,making sure you get exactly the same pressure in both front tires.

    Default pressures

    This might freak some out been running front at 23psi and rear at 17psi since wife wore first oem tire out at 6000mi. in 2010, have run 215/60-15 every since at 17psi , she has 70,000mi. now averaging approx. 25000 mi. per rear now but she rides solo and pulls camper so she scuffs tires bad, riding two up I don't know how long a tire would last ,I would guess at least 30,000. At 17psi. tire wears evenly no more wore out center, currently running General Altimax Rt front and rear.

    I like 25 in the front, was running 18 but didn't like the feel the tires are going to roll off the rim in corners......must be the Baja Ron Sway Bar and Elka shock effect! :-)

    Default Tire pressure

    Here’s a trick my father-in-law told me about. During the war, tires were hard to get and were on ration. To get the most wear out of a set of tires he would mark a line across the tread of each tire from one side to the other with a large piece of white chalk. He would drive in a straight line for about a quarter of a mile and then check the chalk marks on the tires. If there was no chalk visible on the center of the tire he would add air until the chalk line wore off evenly. Sometimes front tires took more air than the rear tires to wear evenly. Don’t forget miss alignment and toe in has an huge effect on wear and stability.
