What size tyres have YOU used.

Tyre sizes for an outback what are people getting away with! I want to go up a profile size on my 96 outback. One tyre shop won't fit them another will provided they won't rub on the struts. And the motor registry technical line is no use as they tell me to read the standards which is totally different to what the general concensus of the tyre shops are.
All I want to know is what tyres will fit after I put in a two inch lift kit. And what size other people are using.
But I realy didn't want to bring up the size of tyres again!

yeah its my argument as well, I want to increase to give me better rolling diameter (have speedo corrector) but no tyre places wont do that as they're following the books, doesnt matter if you have speedo correct fitted. I wanted to install 215/60 16" but they refuse.

Take your rims off your car, and take them to the tyre shop, then they cant question them

That what Im gonna do next time!
I'm gonna get the tyres first then take rubbers off the rim somewhere else and get the tyres fitted somewhere else.

Yeah I've even got some bare forrestor rims unfortunately not the ones I want to use. But to have it legit when I go over the pits I need to make up a sticker with the new tyre sizes profiles speed and load ratings. Go figure.

hey tex my 98outback had about 28.5" tyres that didnt rub on anything except the firewall in reverse at full lock.
i cant remember the tyre size off the top of my head but ill see if i can dig though some old pics and find the size. was pretty big, they actually fitted with only minor scrubbing with jsut lifted springs, but ended up going 2" body, 4.5" strut top blocks as well as the springs by the end

what size rims are they? 16"? cos 28.5" tyres would be 205/75/16 or 215/70/16.

215/70 r16
of the kumho variety, they had to be ordered in for me, and the same for my old black gen1 libtery as well.

Well I found this in the vehicle modifications code of practice;
The overall diameter of any tyre fitted to a passenger car or passenger car derivative must not
be more than 15mm larger or 26mm smaller than that of any tyre designated by the vehicle
manufacturer for that model.
The overall diameter of any tyre fitted to an off-road passenger vehicle or a commercial vehicle
must not be more than 50mm larger or 26mm smaller than that of any tyre designated by the
vehicle manufacturer for that model.
Speedometer accuracy must be maintained for the selected tyre and rim combination to within
the degree of accuracy specified in ADR 18 where applicable.

Although if you have a lift kit bigger than 50mm you can only go 26mm bigger in diameter, But I am yet to find the definition of an off road vehicle!

yeah if you want to comply with all the design rules set out by the government you can pretty much forget about modifying your car effectively. I think most Subaru's would be classed as a passenger vehicle.

At least you can overcome the speedo accuracy issue by modifying your speedo cable....although that would be a modification and therefore probably punishable by death.
