I want to get a set of cooper weathermasters in 185/80, which is about 24.8 inches.

 

the question is how much will it slow down my car?

 

I checked and it will change the gearing to about .264 taller, making first gear about 3.9, if that helps.

i was warned about the loss of power and i can say first hand that the difference between 185/80 and 185/70 was barely noticable if at all. my car is stock, no weber.

 

edit: and your top end might impove a touch.

I'm running 185/75/14, which is just a touch bigger than the 185/80/13. They are mounted on Pug wheels, which are substantially heavier than the 13 inch soob steel wheels. I haven't noticed a drastic power loss. But then again, If I put on some 13 inch soob alloys with little tires on them, I might change my mind. those things don't weigh anything at all:D

I switched from a set of 13" alloys with 175/70's to a set of 13" steel wagon wheels with 185/80's and i could tell a major difference in acceleration.

 

With your EA82, you most likely wont notice at all.

On my turbo wagon, I went from 175-70's to 185-80's. I noticed that I wasn't spinning my tires as much on "slippery" starts, i.e. gravel on pavement.

 

Other than that, it seemed like it still accelerated well, and I didn't notice a fuel economy difference either.

This is easy as hell for me to answer.. considering I ran one of the taller tires on usmb of 235/75R15 (30x9.00R15)

 

155/80R13 kicks rump roast for peeling out and making your BRAT (what i had it on) look alot more powerful.. 155/80's can take you offroad just fine also.

 

165/80R13.. u can now tell the instant difference between 155 and 165 155 was a funner tire than 165.

 

175/80R13.. this is right about where u wanna be.

 

185/80R13.. this is right about where u wanna be.

 

195/80R13.. big and dopey (for stock).. still work ok

 

205/70R14.. This is where you have to start to be critical.. this size and larger wheels/tires will result in gear loss.

 

215/70R15.. These are like pulling a small vehicle behind your wagon, like a waaaay light hatch. You can definately feel the loss in gear now. Its almost gone.

 

225/70-80R14-15.. never ran these.

 

235/75R15!.. your gearing is 95% gone. Horsepower is lost. Bearly tolerable. Going back to 205/70R15 if possible. Btw: O/D on these tires were 30x9.00R15 .. waay bigger than my stock 165/80R13's. (22x6.5R13?)

 

Ok.. btw, i had SINGLE RANGE PUSH BUTTON 4WD! im sure D/R would have ALOT easier of a time. With the 235's on, it was HARD to get moving around, alot of clutch work. Another note: S/R = 1:1 gear ratio D/R = 1.4:1 ... so hassey and someone else with 31x10.50R15 tires have like no gearing so their rigs are pretty much gutless.

 

With enough said.. you will notice alot EVERY time you move a section width to a wider one. Also, I ran EVERY size up there. IMO: 205/70R14 would be the best for our subarus S/R or D/R. (when offroading)

 

Sorry i just posted so freekin much.

Thank you, so it won't slow down my brat much at all then.

Aki:

 

I ran that size snow tire last winter on my 93 Loy 4wd wagon. I liked them very much, and will be using them again this winter. The height was nice for heavy snow, and they performed well in all types of weather.

 

I thought they were actually a little quicker than what I was driving before winter (195/55/15's on Pug alloys).

how many inches would this tire be?

 

205/70R14

25.3 according to the tire calculator
