PVC has more expansion issues RaceDeck type tiles.? I have seen plenty of heaving RaceDeck tiles on these forums but dont recall any heaving PVC pics. Please enlighten us.

First, I am not going to speak as to specific brands but as to the products in general. I will say this. I have never seen an issue with a RaceDeck or Snaplock floor that they did not find a way to resolve. But I am speaking as to two different types of tiles in general. I would also like to say that given that we offer both types of products, I don't have a horse in this race.... Or I guess more accurately I have both horses in this race. I also love both sets of products and believe they both have different applications -- and of course there is some overlap.
Expansion and Contraction
The only time I have ever seen expansion and contraction issues with QUALITY, American Made, garage tiles is when they are either improperly installed or exposed to unreasonable expectations.
With both products you need to consider the time of year. It was 20 degrees when I woke up this morning and there was zero sun. If I put either product in today and left my garage door open in August, I might have to make some adjustments.
If you do not glue PVC down it seems to expand less consistently than Polypropylene. I see more of a rippled effect and I have to physically adjust the tile to get it back to normal.
I don't generally see the issue with polypropylene -- when installed correctly -- but when it does occur it tends to be consistent and fix itself when the extraordinary heat source goes away. If you keep the product in the sun prior to install, load it immediately and leave proper install gaps, this issue is rare.
To Armorpoxy's point the way to alleviate this is to glue the tile down as far in as the sun reaches when you would leave your door open. To that extent proper install will fix the issues there too.
Floor Protection
There is no question PVC tiles protect the concrete better than polypropylene.
Industrial Traffic
If I am driving a forklift on it I am going with PVC. I am going to glue any areas where I might be doing tight 360 turns.
Moisture
PVC does not deal with excessive moisture issues as well as polypropylene. Some do a better job than others.
I wrote an article on this some time back. It needs updating but has some good information in it

Final notes
Both products have pros and cons and neither is right for every project. They key is to know what you are dealing with, make an educated decision and make proper adjustments at time of install.
