You'll be even more excited if you can foot the aluminum .190 Douglas. I'll bet it's another 40$ more than your steel rims. Give them a call and find out the difference, aluminum won't rust or bend like steel and make sure those tires have a tough sidewall.
Here I hit branches and rocks all the time, two sets of tires ordered incorrectly have been sidewall lashed in one days riding - NO BS!! I always make sure to spend the extra 20$ and get XCR, R, EX or whatever dam suffix I have to add to the tire to insure I get a 6 ply sidewall. It's worth it to me....
All our government does is distract us while they steal from us, misspend our tax $ and ruin our country
