Hello everyone hope everyone doing good,

Rear: 315/35 R22

I don't have my usual reference book - it is out of date - but I think you'll find that the wheels are different front to rear. That complicates things enough that you shouldn't trust any answer you get except from a knowledgeable source - that is to say, not here!
 
Tire Rack says you can downsize to 19" wheels with a square setup. You can get a premounted tire and wheel package from Tire Rack

TR recommends the size 275/55-19 for those 19" wheels, but TR doesn't carry any :sneaky:

However, Walmart and simpletire have tires in that size.

So, you might be able to use 255/60-19, which has some good options, including the Nitto NT421Q for only $159 each. Total cost of the package, with TPMS sensors included, comes to $1800, which might still be cheaper than just the tires for your current staggered setup :D

Another option is to buy just the wheels from TR, get the tires from Walmart, and get TPMS sensors from Rock Auto (if you wish to replace them at this time). Sometimes Walmart doesn't want to install tires not of the OE size, but you can get around this by just carrying the rims in to the store.
