I found some tires that are $40 a piece. Theyre cheap ones and, being low on money, I'm not too concerned with what kind of mileage they get me. Normal tire size is 195/65/14. I know that, but the issue is that these tires are 195/70/14. My question is whether or not those will fit without damaging anything. My current tires are near bald and I get a lot of snow in the winter where I'm at so I'd like to get new tires soon. I can't afford the $100 per tire I saw elsewhere, even though those are really good tires. If those won't work, are there any other brands that are cheap? Additionally, one tire has a constant leak, the other 3 have extremely slow leaks. (The new tires are rated for 45000 miles)

Must have made a typo Reader
Stock tire:
P165/65R14

i.e.
http://www.tirerack.com/tires/tires.jsp?tireMake=Bridgestone&tireModel=Potenza+RE92&sidewall=Blackwall&partnum=665SR4RE92&tab=Sizes

miata tire size calculator
shows tire diameter grows to 24.7" vs. 22.4" stock

fwiw: A google search of the site for the size in question:
site:www.insightcentral.net "195/70/14"
shows no hits.

Expect higher fuel consumption [if it does fit] due to greater tire mass. Speedo readout will be about 10% low.

I would not use 195/70R14 mounted on G1 Insight rims...too big.

The questionable tires are over an inch wider than stock and would end up being squeezed if mounted on Insight rims. For this reason alone I would not use the tires. They are much wider (30mm to be exact). I made a scale drawing (attached...) showing how much bigger the tires are.

The questionable tires are almost an inch taller than stock and would throw off speedometer and mpg readings about 8%. And as AbCaRed00 said the added tire weight and non-low-rolling-resistance tires will hurt your actual mileage.

+1. Those tires are way too big. Even if they would fit they would kill your economy and performance.

When we first got my girlfriend's Insight, previous owner had, IIRC, 195/55-14 tires on the car. They were a height match and fit on the stock rims, but really heavy. A 195/70-14 would be significantly taller and way too big.

my car had 195/60 R14 tires in the front and 185/60 R14 tires in the rear when I bought it. Even though the tires were fairly new, the NVH in the car was awful. At 60 MPH, the tire noise was really, really loud. It was so bad, I was seriously considering wearing hearing protection so I wouldn't get a headache from the noise.

Once I got rid of those crappy tires and switched back to the RE92s, the cabin noise inside returned to "normal car" levels.

In my area, Discount Tire can order a couple different Federal brand tires in a 165/65/r14 size that are really cheap.

To the original poster,

Tirerack has our original tire size right now for $79.77/each. Even after shipping it's still reasonable given how long they last, how properly they ride and the benefit of the best fuel economy you can squeeze out of the car with the right size and model tire.

Costco and America's tires run specials on Bridgestones every other month that usually run at $70 cash card rendering this purchase more than reasonable for what you get.

Brakes and tires are two critical items I don't suggest anyone compromise on.

In either case it's best to shop around a bit for the correct size, even if you don't end up buying the RE92. Most large tire retailers will have at least one tire in 165/65r14 to offer.
