3:73's and 26" tires

up to last week I was running 26 x 12.50 M/T's with 4:30 gears and a 4 speed and it wasn't bad around town But I don't do freeways or interstates - I now have 29.5 x 12.50 ET Drags on it and really isn't that much different RPM wise ... but the softer sidewalls makes the back of the car wiggle/waggle like a hoochy dancer ...LOL Have to now keep in the center lane to avoid the gutter ride

The last pic is the 26 M/T's
