Lol, in that case, you shouldn't have any problems, they would hold up, they hold more weight than a regular street tire, but i think you have to pump them up in order for them to do that. I'm not really sure, i asked several times from the guys who run them in here, and never got an answer on how much PSI is good for them, so i'll just get the real front runners for piece of mind. The wheels themselves won't have any issues.
Here is a view of what i did to make them "Tech" friendly, i didn't know if they were going to allow me to use this combo with all the Temporal usage, Spare only, etc, etc labels and tags in the wheels and tires.
"I did a little bit more grinding today because i was obssesed with the temp only use lettering, and removed those messages from the tires as well as the one that said convenient spare and the T before the 145/70/17 , i need to see if i can smooth out the finish in the rubber, but oh well, it's done, i also put some primer on the wheels first to make sure the temp only use letters were gone (english and french words), left the rest untouched "

after this i painted the wheels with primer and black gloss to match the stock color, and also painted the GTO rears as well so i have a matching drag pack
, came out pretty good.
