The point people seem to be missing here is
1: If you bring a set of new tires bought elsewhere to a tire shop to be mounted and filled, they are going to charge you more for mounting, than if you had bought the tires from them.
2: Comparing Windshield Washer fluid to Rimguard as a wheel weight is like comparing Apples to Oranges. Apples and Oranges are both fruit, but not the same. Windshield Washer Fluid and Rimguard and both weights but not equal amount per gallon. Water is 8.34lbs/gal and windshield washer fluid is almost identical, Rimguard website says it is 10.7 to 11.0lbs/gal. Rimguard states their product costs $0.28/lb and washer fluid works out to $0.24/lb. So if your goal is to get as much weight in your tires as possible, you loose with washer fluid and have not saved too much money on a per pound basis.
I think you're missing my point.
Rimguard's guide lists these fill amounts:
26x12-12 8.3 gallons @ 88.8 lbs
18x8.5-8 3 gallons @ 32.1 lbs
I filled each of my rears with 10 gallons of washer fluid for 83 lbs. Lets assume I can only fit an extra 1 gallon in the front instead of 2 like the rear, above what Rimguard says. That's 33.2 lbs, or the same as Rimguard if the dealer does it "by the book."
So you're saying it's worth an extra $200 for 17.6 lbs? That's ridiculous. :laughing: I did both rear tires in 20 minutes with equipment cobbled together in my basement after watching 1 youtube video. So where is the extra $200? You can't tell me it takes the dealer, with professional equipment and no bottles to open and pour, 3x as long to charge a full $60-$80 hour's worth of labor. Even if they did that leaves $170 for materials that I paid $50 for. Still seems like a waste of money.
Now, if the Rimguard dealer pumps more fluid in than Rimguard recommends, that helps a little. Or if the added cost involved mounting new tires. However, my quote involved me doing labor to remove wheels from the tractor to bring them 30 miles away. So my time, plus gas, plus the inconvenience of blocking the tractor to take all 4 wheels off to pay $200 for only 17 extra pounds makes it not even worth considering. I have well over 17lbs in scrap metal laying around if I *really* need to add that much onto the tractor.
My wife weighs more than 17lbs more than I do, and even with her driving we still had traction issues. So 17lbs is not a deal breaker for me.
Another changing factor would be if I could buy rimguard by the gallon and pump it in myself. If I could buy it, even at double the price of WWF it would be worth paying the $80 for 20 gallons for the rear, and $16 for the front. It would be less than half the cost of the dealer doing it, and provide a marginal increase in weight. Since that's not an option, Rimguard is out in my book.
