allseaons vs high performance tires- it really is night and day. During high performance diriving, the Re-92's or any all-season tires just give out and screech like banshees. A high performance "summer" tire will grip, and is more able to handle the power that our cars put out.
Good tires are commonly thought of as a great first mod. Your car will accelerate, corner, and brake better.
all-seasons vs snow tires- again night and day. Especially when you consider that the re-92's are pretty mediocre all-season tires. I kinda enjoyed the Re-92's in the snow, because I could get them to slide around- but my damn abs always activiated in the snow during very docile driving. Now that I have dedicated snow tires, I haven't felt my abs go on once this season.
FastFreddy on the board sometimes has a hook-up for snow tires. If you decide to get another set of all seasons- I have my re-92's in the garage w/less than 7kmiles on them. You can have them for cheap.
