Bigger 15" tires on base 2004 tacoma.

I have a 2.4 - 4cyl xcab tacoma 2wd. On my stock rims which are 15x6 and now have 205s on them, I would like to go bigger without doing any lifts. I don't want to kill engine performance, now I get 27-30mpg but want bigger tires and would like to go 225 or at least 215. I'm pretty sure the 215 will work but I can't find a Wrangler in anything smaller than 225 around here in W..KY. and I'm wanting a more agressive tread without going mudders. Help please.

 

Does anyone know if the 225 wranglers will work ok on my 15x6 rims and not hurt gas mileage. Somebody on here has got to know???

 

I reckon not. Did I ask it wrong?

 

The short answer is you can't get a bigger tire with more aggressive tread and keep the same mileage. It will drop, the question is how much? Maybe 2mpg? You can use the same rims for 225, but I do not know if the tires will rub.

 

27-30 mpg wow, I have an 04 regular cab 2wd and the absolute best I have seen was 25 mpg. As far as the tire size you asked, I run 225/70/15 on the stock rims with no tire rub, but as mentioned above, I lost about 2 mpg. I am actually considering going bigger next time around.

 

wonder if 225x75's will not rub?

 

I've seen 235/75/15 on a stock 1st gen 5 lug. Not sure if they rubbed or not, I'm assuming they did. I had the same size on mine for about a week before I was lifted but I have different wheels as well to stick them out farther. The 225s will probably work

 

I put 235-70-15s on the stock wheels and have not experienced any rubbing. I did lose 1-2 mpg which was worth it considering how much better the Taco does now in a strong crosswind at speed. Much, much better control.

 

Been running 235/75/15 Wranglers on stock rims at stock height for two years now. No rubbing, but I'm mindful of the speed bumps. Lost 1-2 mpg, but between the tires and a set of kyb gas-a-justs it drives like a whole new truck and I'm not looking back.
