I guess I need to wear out the $99 rear T30 close out tire I just put on before the BRG.
Amen to that UP...My only problem is every time a manufacturer 'improves' a tire, it gets less mileage than it's predecessor.
I guess they mean 'improves their profits' ...
Your mileage is impressive. Are you attentive on air pressure? What pressure do you run?6000km on a Metzler rear
12000 km on a Michelin Pilot road 4 GT rear, over the years at least 4 sets and the road 3's before them.
17000 on my first Bridgestone T31. Rear
Thought I'd made a mistake on the mileage but after checking my maintenance records, that figure is correct. Best mileage on any rear tires in ten years of riding the ST.
Looking forward to the T32's and hope Uncle Phil is wrong. But I suspect not.
Quality of tires themselves don't determine a loss, or increase, of tire pressure.Consistantly 42psi. I have pressure monitors but the tires are pretty good at staying at 42psi. I rarely have to add air.
Tires also loose air from permeationQuality of tires themselves don't determine a loss, or increase, of tire pressure.
You must live in an area where the ambient temperature stays constant. That or your bike is in a temp controlled garage or storage, and rarely ride : )
The fluctuation in temperatures between daylight hours and night hours has an effect on pressure, because the air inside them expands and contracts.
The general rule is ... for every 10 degrees in air temperature change will result in one pound of pressure change. If the temp goes up, tire pressure will increase, and vice versa.
Mine sure do. I have to top off every week or two. The rear seems to leak a bit faster.Tires also loose air from permeation
From my experience, style of riding is at least as important as tire pressure.Your mileage is impressive. Are you attentive on air pressure? What pressure do you run?
I've got the T-31's on now.....
Thanks
I changed out my last Metzeler Roadtech-01 180/55zr17 HWM-spec at 22,000km. It was beat. I have another on there now,, and, I have another in the basement ready for next summer (should be good till the middle of 2022). Premium price tires should deliver exceptional performance. Otherwise they are just a rip-off. Cheers,,, CAt'6000km on a Metzler rear
I thought it was just me. It normally is. Since I've been running T31's checking tyre pressures can just about be forgotten. They haven't needed air for months. Previous Bridgestones always required regular topping up.Consistantly 42psi. I have pressure monitors but the tires are pretty good at staying at 42psi. I rarely have to add air.
Mine, too. Every set of tires has done the same thing. I don't know how there are guys who get away with never needing to air up tires.Mine sure do. I have to top off every week or two. The rear seems to leak a bit faster.
Myself also.....I always see a loss in pressure after weeks of use, or non use. I always check before a significant ride. Some don't?? A few years ago, my friend and I went for a 2 hr ride through some twisties at fairly high speeds. I was surprised at his riding, he's older than me. When we stopped to eat, he said his bike felt loose on the turns. Out comes my air gauge and guess what I found? 22lbs of air in his freaking tires!!!! (same size bike as mine)Mine, too. Every set of tires has done the same thing. I don't know how there are guys who get away with never needing to air up tires.
Similar here with my T31s, and previously the T30s. I check them religiously, but seldom have to top off - except when ambient temp changes.I thought it was just me. It normally is. Since I've been running T31's checking tyre pressures can just about be forgotten. They haven't needed air for months.
Upt'North.
Well you may be close, just priced the T31 and the T32 . My source was $158 and $175 respectively.I guess they mean 'improves their profits' ...
Most likely the low hanging fruit was picked a long time ago in terms of tire technological advancement. Now the increments are going to be smaller, especially when you take into account that the tires have to be affordable.If I remember correctly the rubber that hits the road is about the size of a credit card. So 13% may sound like a lot but in reality it isn't much and how do we really know is not 12%. And the extra 10% of a 6,000 mile tire, an extra 600 miles, well that remains to be seen AKA "I always ride on perfect roads" No doubt it's a better tire but after 3 -4 years running you would think they could do better than 10%. I would be shocked if my mutual fund only increased 10% after 4 years. IMO
