Hi, Claude. It's a bit involved but, since you have a reasonable need to know, I'll explain. I had two 16 x 8 GTA wheels on the front of my WE4 with the tires you are buying on them. I had a pair of 15 x 8 "look alike" GNX weels on the back with MT drag radials on them which I ran all the time. I also had two spare 16 x 8 GTA wheels with no tires on them in the garage.
I needed a matched set of real street radials for the trip to Bowling Green in May. So, I bought a set of Sumitomo HTRs and had them mounted on the 4 16 x 8 GTA wheels. (245s in front and 255s in the rear) and removed the Kumhos you just bought.
I also sold the GNX look alike wheels (actually BBS wheels) with the near bald drag radials on them to a local club member because I want to have my new race tires on the same GTA wheels as my regular radials. So now, I have 4 GTA wheels on the car with the new Sumitomos on them and
I need two more 16 x 8 GTA wheels to mount the new BFG G-Force drag radials IIs I just bought. I went with BFGs this time because the tread pattern has a more streety look and also resembles the front tire tread pattern better than the MTs would have.
Is that clear as mud?
