205/75/15 tires on a stock outback?


Recommended Posts

Hopefully someone who has run them will chime in.

 

And I'm sure someone here can point to a tire size comparison site.

 

But you realize what the 70/75 thing is? It's called the aspect ratio.

 

It basically means that the sidewall is 70% the size of the tread - or in this case 75% the size of the tread. So it'll be less than 10% wider

 

I'm sure someone out there works at a tire shop. But I'm often amazed at the folks that don't realize what this number actually means. If I'm incorrect someone please correct me(like I have to ask).

Does anyone know if I'll have any trouble running 205/75/15 size tires on my stock 96 outback?? I'm sure this is covered in here somewhere, but I cant find any info.

 

Thanks

 

this tire would be .80 inches taller, that's .40 inches of radius. it's the top half of the tire rubbing that you worry about. i think that's a lot. the difference between outback stock and legacy stock is about .77 inches of radius. so this is half of that.

 

it will probably rub in tight turns.

Hum yeah, I think I would be more worried about the rear tire rubbing on the strut.

 

In my tire search I have narrowed it down to two different light truck tires...

 

The Yokohama Geolandar which come in the stock tire size http://www.tirerack.com/tires/tires.jsp?tireMake=Yokohama&tireModel=Geolandar+A%2FT-S

 

Or the Firestone Destination which offers the 205/75 sizehttp://www.tirerack.com/tires/tires.jsp?tireMake=Firestone&tireModel=Destination+A%2FT

 

I have a friend with a 97 Legacy and he has the scorpion springs which raises his car higher then my stock outback. Hes running the 75 profile Destination tire with no problems.

 

I dunno, maybe I'll the toss a set of All season tires on it and call it good. It's almost summer anyway.

 

Here is my friends 97

Yes, aspect ratio is that of the tire sidewall to its width. However, both of the tires in question are the same (205mm) width, so it's the height (and slightly different positioning of the maximum width point) that will vary. Here's a link to an online calculator that provides comparison data, including the effect on speedometer readings: http://www.net-comber.com/tirecalc.html

My brother runs 235/75/15 tires on Leagcy w/Outback struts. That is pretty much maximum before you run into a clearance issue with the spring perch on the strut. Now his rig is lifted, for body clearance, so youcouldn't run that size on a regular Outback.

 

My point is that a 205/75/15 will clear the spring perches just fine. I doubt it will rub the frame in turns either. (the 235/75s just BARELY rub) The one place it WILL likely rub is at full compression, if the wheek is turned, it may hit the fender edge.

Well I went with the Yoko Geolandar 205/70/15. They look great on my car, very aggressive looking. Only problem I have noticed in the 20 miles I have driven on them is they like to follow the groves on the freeway. So it kinda tosses my car around a bit. Strange. :confused:

I assume you're talking about the Geolandar A/T-S. They, like many tires made today, have a tread pattern designed to minimize hydroplaning. Unfortunately, the water channeling grooves often make it more likely for the tire to 'track' road grooves. If the problem is severe enough, you might go back to where you got the tires and see if they'll exchange them for something with a different tread design.
