Tires are available

[GT@50]

One dot will be for the heavy spot. Sometimes another dot is for a high spot. Rims are marked too. I can never remember what's what and neither can the tire guys

Long time ago my 1990 Miata had red dots on the tires lined up exactly with black dots on the wheels. That's how the car was delivered new. The tech told me the tire dot marks the lowest point on the tire because tires can almost never be perfectly round and so are the wheels. So the two dots need to correspond with each other for a perfectly balanced tire/wheel comnination or something along those lines. Never confirmed that because it sounded like a good explanation until today when I heard unconvincing explanations from the shop that installed my tires.

A new topic for Hudson1234 on BaT instead of tire date codes what’s the dot?

That guys has some weird obsession.

Did they high speed balance? The tires are supposed to be good in excess of 200 mph if high speed balanced. Mom and pop may not have the right equipment. As I remember. the two dots indicate the heavy spot on the tire and the light spot on the wheel (or vice versa). and just give a general alignment for the mounting staff. It does save time and extra lead weights. The Bridgestones are pretty equally balanced straight from the plant. I will send the Grey Ghost a note so he can chime in.

I have never had tires balance with less weight.

BBS wheels help a lot, I am sure.

When we were at Saleen SSV the tire wheel station guys were mounting and balancing. They were applying to
the little dot stickers. I presumed they were weight points. I still have them on my original set of tires wheels from my car and my sons. I will look when in shop today.

With due respect. What ever you like is ok by me
But I’m sticking with what I know

The bad news MUST be true!

 

[reiner]

have Nitrogen in the tires for my CJ3 and it's use in aircraft tires. 1. high altitude freezing 2. disipates through rubber slower than oxygen. 3. No moisture so not as much rubber degradation. 4. On landings tremendous heat can build up.

No one fills tires with oxygen.

 

[PeteK]

The reason for using nitrogen in aircraft tires has to do with high pressure. Except for light aircraft (think Cessna, Piper, etc.), aircraft tires operate at very high pressures—hundreds of psi. It’s much more practical to use a high pressure gas cylinder/regulator to fill them than an air pump, and if you’re gonna choose a gas that is readily available in high pressure cylinders, cheap and relatively inert, nitrogen is the most practical choice. The kinetic diameters of N2 and O2 are so close that there’s no appreciable difference in permeability through rubber, but pure O2 would probably break down rubber faster due to it’s much higher chemical reactivity.

And blow up when heated

I guess this isn’t new news, but Discount Tire bought Tire Rack a couple years back.

Hopefully Bridgestone keeps making our tires for Ferrari so we can continue to add miles to our GT’s getting close to needing a set of rears guess there’s no better time than now to order

I have one new rear I bought as a backup in 2022 if anyone just needs one. Think 2022 build date

Ready for tires that’s a good thing made a call to Bill at Radial Tire next day service they are amazing and great to deal with. Thanks Ferrari for making the tires we need available through Bridgestone

Bill Is the best ! Also the best prices and build dates!

Ordered a set of Bridgestone tires from Bill a few weeks ago. Tires arrived promptly and had them installed today at a local family owned tire shop (not chain) which has been in business for decades. Had the tires mounted on the standard wheels so I can preserve the option wheels that came with the car. Plus I like the standard wheels more. After the tires were mounted I noticed the little yellow dots on the tires didn't line up with the valve or the with black markers on the wheels. Asked the tech mounting the tires if he knew the significance of the dots on the tires and wheels, he had no idea what they represent or what to do with them. His senior supervisor said they are there just to let the factory know "they're done". The store owner knew vaguely what the markers represent but said he never paid any attention to them for as long as he's been in business. Question to the experts here, what do you think? Shouldn't these markers be used in mounting and balancing the tires or can they be totally ignored?

It is my understanding that the yellow dot should be lined up with the valve stem. Would you mind sharing the sizes and model number he sold to you as i have called Radial Tire and they seem to be in the dark. Bill is not there.

There is plenty of info on this Forum. Just do a search.
