Title: Poor Bob...
Post by: Justin B. on June 17, 2016, 01:37:18 PM
I see that it's supposed to hit around 120 degrees in Phoenix this weekend!!  When do motorcycle tires start to melt and merge with asphalt?

Bob, you need to move somewhere cooler, like Texas!  ;)

Seriously, though, be careful...

I'll take the near 100% humidity we have in FL because the temps rarely get over 100*

I lived in Oklahoma for a year when I still belonged to Uncle Sam and that was the hottest I have ever been. I still remember the shock I felt leaving work and leaving shoe prints in the asphalt like I was walking on beach sand.  No thank you!

It gets hot everywhere in the USA whether it's the dry heat of the desert or the mugginess of the South, you adapt to your climate.

Having worked in Phoenix in the summer time I must say it's in a league of it's own. That being said, with a population of 3 Million in the area,  the heat isn't driving anybody away!

Well, it's like other extreme in weather, you don't expose yourself to it any more than you have to .

I'm going to take the '81 R65 ( it's got an oil cooler ) out Sunday afternoon, about 5 PM hottest time of the day and see what I get for tire temps in the 119-121 F , 48-49 C. air temps we're forecast to have .

Last time I tried this in these temps, I put my Harbor Freight infared thermometer I side my mesh jacket, for quick access when I got home .

When I got home from work at 3 PM,  took the thermometer out and it showed an Error code, had to out it in the freezer for 10 minutes before it indicated correctly, but by then the tires had ' cooled ' down so not an accurate temp reading .

One thing people don't realize, is how hot the road surface temps are in these temps, surface temps can surpass 200 F, 95 C .

You need protective gear for the road temp as well as for abrasion !!

And yes you can cook an egg in these conditions just use a dark frying pan !!!! ;D

This is the time of year a lot of batteries quit with no warning as well .

It's also prime time of the year, for ' road alligators ' that's the thrown tire caps from heavy trucks !!!!

' Tar snakes ' are also an issue, that's the road tar that is put on cracks in the asphalt pavement, you can feel your bike slide a bit in a turn when you cross one .

Well at least it beats snow and ice !!!! ;)

For a cold weather northern Brit, I was hammered by the heat I felt when I was in the US last year. For someone who is used to hot meaning 85f once the temps got in to the high 90's I suffered. It reached a point in Oklahoma when its was 100+ with 70% humidity I could not wear my mesh jacket because I was getting so hot it was making me drowsy, not a good thing on two wheels. How you lot over the pond handle that sort of heat for months on end astounds me, when its hot here, its not in the same league as your idea of hot.

You get acclimated to it, I lived in Chicago for 37 years before moving to the Phoenix area .

One summer here and 105 F, 41 C.,  feels normal .  ;D

I'm never leaving, the heat is what prevents this place from becoming another southern California . ;)

Temp extremes go both ways. Anyone who has ever worn a uniform knows that their respective government has a twisted sense of humor.

I went from saying goodbye to my family in So FL, USA and 90*f temps to Fairbanks, AK with an actual temp of -45*f in the span of 8 hrs. I don't care what religious faith (or none) you follow, you have to admit someone has a weird sense of humor.

Yes I adjusted to it and acclimated myself to it, but I never got to liking it. JHMO but I feel more comfortable in a climate similar to what I grew up in. I spent time in the arctic and got used to it but never really liked it. I also spent time in hot, desert areas and again I got used to it but never liked it. I also spent time in hot, tropical environments and felt right at home. Maybe its just me but I think that the environment you are raised in plays a big part in where you are comfortable living your life.

I took the '81 R65 out yesterday at 430 PM 118.4 F, 48 C. air temp , road surface temps were 179 F., 82 C., after 20 miles, 30 km at 80 mph 130 km/h, I stopped and took temp readings .

Front tire 195 F. 91 C., rear tire 203 F. 95 C .

Oh yeah, they stick like Velcro at those temps . ;D

These tires are Metzeler Lazertec .

I have a temp indicating oil dipstick, oil temp, 300 F, 150 C  .

Crazy conditions

At least it proves that the rear runs hotter than the front. I wonder what the tyre pressures were at those temperatures.

I am from a little tropical island so riding in a hot wet weather with full gears on wasn't really new.

But riding in a cold weather was a totally different story.
