Spyder: 2013 RT-L
Type of Riding: Spirited Twisty ryding; long/hot distance touring; occasional track/test work
Suspension: RonBar; Laser Alignment; ECU Upgrade with inlet tract & exhaust mods
Front Tires: Oz spec Kumho Solus 175/55/15, set to 14 PSI for winter riding, 15 or 16 PSI in summer/hot ambient conditions
Rear Tire: Oz spec Michelin XM2 205/65/15, set to 16 PSI for winter riding, 17 or 18 PSI in summer/hot ambient conditions
Current Mileage: Fronts - 'embarrassingly waaayy more than most' miles; Rear - 'embarrassingly waaayy more than most' miles. They still look very good with even wear & no heel/toe
Comments: If there are changes warrant it, I do adjust my tire pressures to suit any changes in load, ambient temps, road surfaces/conditions, &/or what I'm doing - generally weekly, sometimes daily, or if the changes in any of the variables are significant enough, even more often; and I occasionally swap these tires out to do maybe 1000 miles or so on others as I test/evaluate them, but those miles aren't included in my logged miles on my 'daily ride' tires. This set of tires has been the 'daily riding' set on my Spyder for a few years now, because I only average about 20k miles/35k kilometres a year these days, and they are all about 2/3rds worn, very evenly across the entire tread face; the lower winter pressures I run help to maintain their exemplary traction levels in the dry or wet; and they still particularly suit my need for Sport/Touring All Season/All Weather tires that see a lot of long distance travel and significant amounts of 'unsealed road' use. The Kumhos do tend to get harder as they age, so they need a little lower pressure now than they did earlier in their life in order to maintain their traction levels, especially in the wet; and they are probably a little closer to needing replacement than the rear Michelin is, altho they all still have more than 3mm of tread depth atm. I expect that I'll probably end up changing this full set of tires out before they're even close to 'fully worn out' (or at/below 2mm of tread depth) at some stage during the coming year, especially if we look like doing anything much in the way of long distance &/or hot weather travelling away from home; and when I do, I'm planning on going Michelin all round, with XM2's up front in a 175/
50R15 (the Michelin's 'nominal size' is a little bit taller than most and that size is closer to the Kumho's 175/
55R15.
