What specific's are you looking for in the stock tires????
Grippy'ness?? Get the Sumitomo's (320AA treadwear rating, but they will wear sooner)?? The Falken's & the Michelin's I believe are 400AA's & the BFG's are 420AB's I think??? Anywho, harder rubber compound, but they will last longer. Not quite as grippy, IMHO.
Tread looks?? Get the Falken's with their direction tread design (has that V design that is supposed to channel water better). The other 3 tend to look like normal passenger car tread designs
Price??? The Michelin's will be the most expensive, the others are pretty close in price range, but not as expensive as the Michelin's.
All 4 are M+S rated. Since you are down in Portland, OR & the weather is pretty similiar to us up here in Seattle, all 4 of these will be fine.
The BFG's are available in raised white letters. The other 3 are only blackwalls.
Based on the above criteria, what specific's are most important??
(DOH!!!! I just now remembered that you just recently turbo'd your 5MGE. Thus for traction purposes, I would get the Sumitomo's, but Jay Balducci is running the Michelin's on his 85 7MGTE).
(For information purposes, this is my tire history for the Redpra on the stock rims): Dunlop SP Sport D3's (the car's 2nd set of tires & they came w/ the car when it had 75K miles. They were just about worn out & I only had them on for a week or so). Goodyear Eagle ST's (235/60's. They lasted pretty long, but I made the DUMB mistake of only rotating them ONCE... Thus I learned the hard way about treadwear). BF GoodRich Radial TA's (Back to 225's. Lasted longer, due to tire rotation). Yokohama A509's (I discovered the joy's of sticky 160AA tires, and the pain's of driving them in the snow, because they are not M+S rated), and just recently, another pair of Yoko A509's).
I am on my second set of sumi's, I find them quite grippy in the dry, safe in the wet and dangerous in the snow. I am in eastern NC so snow isnt a big issue for me and once balanced and trued they are reasonably quiet. I'm sure some may believe in tru-ing but it works for me.
The 245/50 BFGs are about an inch shorter in dia and an inch wider than a stock 225/60. It makes the car sit lower and they handle pretty good too!
A little more "heavyness" in the steering tho. Mine are getting pretty worn now, and in the dry they handle really well. Don't forget the speedo reads a little fast (~5%) with them too. Its like putting in 5% lower gears. Ie 4.10s -> 4.30s or 4.30s -> 4.56s
