Yep, UV is also bad for tires, at least as much as it is for paint.

I ran the V700 tires all the time even on the street so I didn't have to buy another set of wheels and swap just for autox events. They typically lasted about 5,000 miles overall, but both of those cars were light. FWIW, when the OEM tires on my Mazda 3 wore out I installed Conti PureContact...

About 25-30 years ago, racing in SCCA, everyone ran either BFG R1 or Hoosier tires. Then Kumho came out with the V700, which had comparable traction. Great for racing, street legal, lasted longer than either BFGs or Hoosiers, and less expensive. I ran them on a 3rd Gen RX-7 and a Panoz Roadster...

This gun wasn't on the streets, it was in the glove box. ;) Seriously, best advice given here is to drive the car back to where you got it, drop it off and tell them why. It's their problem, not yours.

I didn't say that I cared whether people use medication. I said that medication is not needed to make a lifestyle change, which is a simple fact. If some people are unwilling or unable to make those lifestyle changes, then medication may help them. However, medication leads to the question: Is...

The video got at least 2 simple changes right. Since the 1970s, people are more sedentary, and they eat more junk/prepared/processed/packaged food. Whatever other causal influences may be at work, these two are sufficient to explain most of the increase in obesity. And fixing these two is a...

Fast-forward a few years, the car still had this issue. It never got worse, and since it never happened after warming up, I knew it couldn't be anything serious like wear or bent parts. I began to wonder whether the root cause was the engine, rather than the clutch or mounts. After a cold start...

A few observations from the discussion: I don't care whether we use standard or daylight time. Just pick one and stop switching it twice per year. The closer to the equator you are, the less difference it makes since the days are closer to equal length year round. The US Constitution gives...

Glad to see some places stopping this ridiculous outdated practice. One strange aspect of DST is that on 3/8/2026, 2:30am never happens. And on 11/1/2026, 1:30am happens twice. This can create problems for data processing of streaming event data. Of course that kind of processing usually...

She was slow to respond to the initial instruction, and her radio skills and knowledge were sub-par. But I've heard worse pilots than her around Seattle approach and the controllers are more patient and helpful. I agree with Captain Steve's analysis overall. The controller was out of line - if...

So 4.5 gallons went out and 6 gallons has gone in? Sounds like 1.5 gallons has been lost (leaked or burned).

That sounds like a lot. But it depends on the total coolant capacity, which is? And how much did you add after draining it? If the losses are a significant % of the total capacity, then the engine must be losing coolant - either leaking or burning. One thing that can be helpful is take a 3 oz...

I concur with @wings&wheels and @oldcodger. In some cars it's normal for a coolant refill to be incomplete because there are air pockets in the system. If the pockets are small and the coolant is mostly full, driving the car as normal will eventually resolve this as the flow of coolant pushes...

For sliding parts, like semi-auto and Garand actions, I find a light grease (NLGI #0 or #1) with a tackfier agent works great.

As a general rule of thumb, the amount of water created in a typical gasoline engine is approximately equal to the amount of fuel burned. The water is created by combustion so most of it goes out the exhaust pipe, but some gets into the engine since the piston ring seals aren't perfect. So if...

Like most aviation incidents, it involves multiple factors that line up through holes in the "swiss cheese". They departed in marginal conditions without an IFR clearance, expecting to get it in the air. Immediately after takeoff they experienced worse than expected weather and maneuvered to...

That top pic looks like Slick Rock park in Moab.

Meet Frankenbike: I inherited my brother's old Trek 330 from the 1980s. It sat collecting dust for a few years because I didn't know what to do with it. Then I remembered I still had the old Mavic E-2 rims from the Vitus 979 that I raced in the 1980s (back in the day I rebuilt those wheels...

I generally agree, though some bike stuff isn't designed or built with as much durability as it used to be. One obvious example is the Shimano cranks debacle. In days of yore they were were forged from a single piece of metal and they last forever. Then Shimano started gluing them together to...

Succinctly put, and our disagreement boils down to different assessments of typical road surfaces. You believe in always using the widest tire that will fit on the bike/wheel because no surface in the real world (even smooth pavement) is smooth enough for a narrower tire to be faster or more...
