Default How big is too big?

I want to upgrade my wheels and I was looking at fitting 215/70R16 A/TS (possibly 215/80R16 if it would work) I was planning on combining it with a 2 or 3 inch lift. Sorry if this is a bit of a silly question, I am new to all of this and want to learn

G'day & Welcome Brownie


21565R16 is a common upgrade as your tyre size is limited by the spring perch because it's position does not change with a strut top lift.


There's a couple of sticky threads that you may want to look at above.

don't forget the legalities in NSW, either.

< 7% diameter change without certification.

The bigger you go the ince going from more strain you put on everything & the worse your ability to climb will be.


I've noticed since going from 215R6016 to 21565R16 that I have to drop back a gear sooner when climbing.


If you want more rubber, consider dropping a rim size to 15", then you'll be able to get MTs on it.

You have a SG Forester which has the higher spring perch. 215/70/16 is by far the most popular size for lifted Foresters & with a 2" lift will fit without rubbing.


225/70/16 will also just squeeze in under the spring perch but you'll need to flatten the pinch weld behind the front wheels, possibly a little trimming in the rear too


For tyre regs, the 7% rule doesn't apply to Foresters or Outbacks in Victoria, NSW & Queensland. In these states, you're allowed tyres with 50mm bigger diameter giving 1" tyre lift. This is in addition to 50mm strut lift, ie 75mm total lift is completely legal! Unfortunately, this doesn't apply to other Subies or other states. Hopefully, as they keep updating the laws, all the other states will come into line

Mine rub slightly on something on full lock and they're 215/65/16... .


Well.. something makes a noise anyway. maybe it's my steering.

Just squeezing in is not really good enough because with tyre flex your tyres will rub on the spring perch; mine did!

So did my 21565R16s; they rub on the inner wheel arch.

Lifted or not they should still fit - not that I recommend that size of course.

I'm surprised they're rubbing, 215/70/16 don't rub for most people depending on the brand

A lift kit doesn't stop tyres rubbing on the spring perch of course, but it does stop them rubbing on the wheel arch with the suspension compressed like when you go over a rut

Would an offset wheel help avoid rubbing do you think?
