We bought a new 2012 Outback 312BH, now I want to replace the 15” wheels and Road Rider 50mph max speed tires with new BF Goodrich Commercial T/A 245/75R16’s and new wheels. The problem is I need to raise the trailer to make room for the larger tires. What is the preferred method to do this? The axles are already below the springs and I only need 2 inches. Can I just replace the springs with larger arc springs? The springs that are on it look overloaded already. They have a slight bend at the axle I’m not sure if this is normal.
Thanks for your Help.

Can't help you with lift advice but I'm pretty sure your tires are ST tires and thus rated for 65mph not 50. (probably 50psi)

Wow, are you sure you really want to do this? I would just recommend replacing the******tires and roll on... Because you have to remember the gap between the tires as well. If the tires get to close, it will create it's own set of problems, not too mention fitting them into the wheel wells.
Best of luck, but sounds like you should have figured this out before you laid out the cash...

It looks like that kit from PPL would work, but would ask, is there any possibility of modifying the wheel arches directly above the wheels ? Or is it the flat floor ?

Thanks for your Help.
the 312BH is simiar weight yand length to our 295RE. Factor Tires are rated for well above the trailer GVW, over 10,000lbs vs. the GVWR for the trailer in the 9000lb range, your axles are probably rated at 4400lbs each. once you subtract 1000 or so on the tongue, you should have plenty of margin. We've put over 10K miles on our 295RE, about 8000lbs on the axles, and tires are wearing well and evenly. Probably will get another 15K mile or so out of the tires. Just keep them inflated to 65psi.

Thanks harper223 I have been looking for that all week.
ST225/75r15 Road Rider tires have a speed rating of 50 mph.
Road Rider ST Tires
I have not purchased anything yet I want to make sure I can fit them first.
It’s a flat floor but that’s not the problem the slide out has a bar (part of the rack and pinion) that is a little too close for me.

I am with "downtheroad".
Speed
•All "ST" tires have a maximum speed rating of 65 mph.
I also read this and find it interesting.
Time
•Time and the elements weaken a trailer tire.
•In approximately three years, roughly one-third of the tire's strength is gone.
•Three to five years is the projected life of a normal trailer tire.
•It is suggested that trailer tires be replaced after three to four years of service regardless of tread depth or tire appearance.

I can’t find any other info on the tire’s other than the link I posted and it looks like the speed rating is 50 I know the sidewall list 65 psi
Ether way the 65 mph max speed on ST tire is way too low IMHO. I like a safety factor and I’m willing to pay for it. I wish the RV companies cared enough about their customers RV experience to offer better stronger wheels and tires. I have read way too many post about tires that fail in the first year, it will always be on my mind while I’m towing. So if anyone wants a new set of 15” aluminum wheels and tires let me know they are for sale.

I agree with "downtheroad", if you have ST tires they are rated for 65 MPH. I would recommend that you verify this before you go to a lot of expense and trouble.
Also would doing the modification to suspension system VOID your warranty?
