subieman Posted February 6, 2009 Share Posted February 6, 2009 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 Link to comment Share on other sites More sharing options...
bratman18 Posted February 6, 2009 Share Posted February 6, 2009 Isn't that the stock size? I thought it was, if not very close Link to comment Share on other sites More sharing options...
subieman Posted February 6, 2009 Author Share Posted February 6, 2009 Stock size is 205/70/15 Link to comment Share on other sites More sharing options...
bratman18 Posted February 6, 2009 Share Posted February 6, 2009 Stock size is 205/70/15 ahhh, ok, I knew it was close. I say they will fit. Do you know how much bigger they are from stock? Link to comment Share on other sites More sharing options...
davebugs Posted February 6, 2009 Share Posted February 6, 2009 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). Dave Link to comment Share on other sites More sharing options...
bratman18 Posted February 6, 2009 Share Posted February 6, 2009 I just looked it up and they are a little less than 1" taller. and yes the width is a little different too. Link to comment Share on other sites More sharing options...
johnceggleston Posted February 6, 2009 Share Posted February 6, 2009 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.

subieman Posted February 6, 2009 Author Share Posted February 6, 2009 (edited) 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 Edited February 6, 2009 by subieman added picture Link to comment Share on other sites More sharing options...
OB99W Posted February 6, 2009 Share Posted February 6, 2009 [...]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 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 Link to comment Share on other sites More sharing options...

Gloyale Posted February 6, 2009 Share Posted February 6, 2009 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. 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.

subieman Posted February 7, 2009 Author Share Posted February 7, 2009 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.

Only problem I have noticed in the 20 miles I have driven on them is they like to follow the groves on the freeway. [...] 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.
