Can't imagine even serious performance tires would still be that hot unless your garage is at the end of the track...

Having said that, I still think the tiles are better.

Anyone try POR-15 on their floor?

I agree the tiles look great and are much softer under foot, but is that the best price? Does it really cost a grand to cover a 3-car garage?

bear in mind also that the X5 tires or your SUV tires are on a much harder compound... performance tires such as S03s on the M3, the PS2s on my M5, and PZero Neros on the Boxster S are sticky by nature. Just because something is heavier or has a larger contact patch will not necessarily lift epoxy based paint even with full painstaking etching which I did and priming and multiple coats. My dearly depart X5 with the sport package NEVER lifted anything... and try using a pyrometer... no much how much I beat on the X5, it will still never get as heated as the performance tires in the other cars.. Just a thought....

BTW.. did Brentwood or the Delta ever get up to 110 last year??? Pleasanton here gets hot but definitely not 110..

Lot's of misinformation you got there. Speed rating is the compliancy of a tire and the material to handle speed AND friction. Friction is what causes heat.. not sidewall or tire flex. M5 do not come in 19s. S03s on the M3 in 19s comes in W rating which is rated good up to 168 miles not 149. The old speed rating system with Z rated tires are tires good for 149 and up. Last time I checked you my X5 came with 18's with an H rated tire on the SPs. Take a look at the temperature rating of the tire. It will tell you a lot.. Besides, that's also a moot point since the compound of the tire caused a lot of lift also... Bottom line, back to the orginal debate.. I park my cars in your garage... it will lift whatever epoxy based paint.. guaranteed. Hence me going to composite tile. If you think that's too expensive, that's your perogative.

This is the best/most professional exchange I have seen on this site...if only this were the standard rather than the exception!

I would definitely go for a tile solution over having to go through all of the prep work and effort to paint the floor, not to mention the potential maintenance effort. At 30% off that tiling is a steal for my 1 car garage at my townhouse (22x14).

Still incorrect...

What you quoted was for the E60's that is NOT out yet. I have a E39 M5 but of course, I would love to get a E60 M5 soon.... standard tires that come with 02 X5 3.0 with SP were not the diamaris.. they were Michelin Radials 255 in 18's and all the guys include MD, Supergreg and KewlX5 can chime in on this...listing the tires that come with the 4.8 is well.. just a little different... the M3 wheels are 19's and they are forged... BMW upgrade from the standard 18's wheels. Both KewlX5, Jude and I have the 19's... and yes I went through 3 sets of tires on that car with the last being the aforementioned tires. Again according to the laws of physics/thermodynamics, friction is what causes heat. The lifting of epoxy based paint or anything else for that matter is really where the propensity for the paint to stick to the tire is > than that to stick to the ground.

on your point about speed rating, when are you going to be at a 100% load of the tire at speed??? W rated tires as shown in the chart has been tested good up to 85% load as per DOT rating system which is what most passenger vehicles will be (unless you got a bunch of 400lbs guys sitting in your car)
You talking about two completed different variables in the last exchange. Heat vs load. Again... heat is generated by friction. Limit of the tire is per the temperature rating of the tire.

I do not see a career in fact checking or law in your future.

The X5 referred to

"Myself and my two neighbors have had the Griot's paint on our floors for over 3 years in the SF delta where temps get to 110 in the summer and drop to frost levels in the winter. We park a Tahoe, Volvo wagon, Minivan, F500 commercial vehicle, X5, 300M and VW Beetle on the floor every day... amount of paint lift... ZERO. Prep is essential!"

as not lifting the paint was mine and I do not own an '02 X5 and definitely not a 3.0...

Your tire size is irrelevant to the speed rating which is the same...

Why would anyone buy a tire based on 85% load? Especially an SUV which is meant to tow and load more than 400lb men...

Regarding your thoughts on friction... in the words of Charlie Murphy... wrong, wrong... you incorrectly believe that it's the rolling friction that makes your tires warm due to an elementary belief that they are rubbing the roadway. That is called sliding friction and if encountered constantly on a roadway would decrease the life expectancy of tires to several weeks. In the interest of those who are become bored with this exchange (myself included) I will not explain thermal dynamics, but trust me when I say that load and flex are creating far more heat than contact.

Oh and by the way if you still think you can lift a correctly applied epoxy floor contact the BestValueinPainting.com out of Fresno they can lead you to one of their clients like Pirelli or Costco. There you can attempt to lift their paint.

We could be wrong but I doubt it.

Now I am certain you will rebuttle, but this concludes this thread for me. Look forward to seeing pictures of your tile floor and how the process went.
