My version of ecomodding...
 

Hi all, I see on here a lot of you are ecomodding for the highest fuel mileage your car can possibly get, some spending good money to get those last few mpg's. I however was drawn to ecomodding because I'm pretty frugal (sometimes downright cheap.) I have adopted some new driving techniques to better my mpg's however I save money more by doing most of my own vehicle maintenance, but the biggest savings I come across is buying used tires. Now it may seem crazy, but hear me out. Buying inexpensive tires for my car new would be around $350-$400 installed, buying some low rolling resistance tires would cost a bit more, maybe $500. However I come across a lot of used tires in my line of work, some I admit I get off craigslist, but finding the right set can save me quite a bit of money. For instance (I live in nh, I have $90 into a set of snow tires for this year, they were previously used for one season and I was able to negotiate them down from $150, and my summer set, I'll end up having (once mounted) $130 into them. That amount of savings more than makes up fabricating a grille blocker or purchasing smooth wheel covers for a couple more mpg's.

Thanks for reading lol, I'm not good with structuring what I write so sorry if it's cumbersome to read. What do you guys think?

Nothing wrong with that I got a used set of tires on my truck for $100 that would have cost over $1000 new

I haven't bought a NEW set of tires in about 20 years; there's little point to a modification if it's not going to pay for itself.

I can see it being false economy in some cases unless you can mount and balance the tires yourself. Good new tires for my car can be found for as little as $40 on a sale because they're pretty small tires. Mounting and balancing make up a significant portion of total cost and happens more frequently if using used tires. Worse, is be missing the part of the tires' life with the most grip and traction. So, I'd add some cavests.
