The Nissan Path

There are four models, for the new 2013 Pathfinder with two wheel/tire sizes. Here is a quick summary.

Pathfinder S - 18" x 7.5" Aluminum Alloy Wheels with P235/65R18 tires.
Pathfinder SV - 18" x 7.5" Aluminum Alloy Wheels with P235/65R18 tires.
Pathfinder SL - 18" x 7.5" Aluminum Alloy Wheels with P235/65R18 tires.
Pathfinder Platinum - 20" x 7.5" Aluminum Alloy Wheels with P235/55R20 tires.

They should have wider tires on the 20". In front wheel mode, I think it is too much weightand will wear bad. Also with all the round-abouts I do not expect mine to last too long.

They are quiet while driving and seem to have adequate grip. Rain is good. Have not had in snow yet.

The important thing is the offset and hub bore if you're considering aftermarket (or another Nissan/Infiniti) wheel.

The offset is 50mm on the stock 18" and 20" wheels.

The hub bore is 66.1mm. Gotta keep them hubcentric.

We have a Platinum with 20" (obviously). I got a set of Murano "5-Y" 18x7.5" wheels for my snow tires. Exact same diameter, width, offset, and hub bore diameter as the Pathfinder 18" "5-horseshoe" wheels.
