A: I certainly hope the tire dealer and your regular mechanic use a torque wrench when tightening the nuts. Typically, that is between 90 and 120 foot pounds. Additionally, sometimes there is a reaction between the steel lug nuts and the alloy wheels that complicates things. I have a 12-volt impact wrench and keep it in the trunk for those special occasions.
A: In general, tires that are slightly over-inflated present no danger. Under-inflated tires on the other hand, may flex a lot which causes friction which gets them hot and may lead to tire failure. By the way, don’t fall for the bogus service of replacing the winter air with summer air. I admit to using that stale practical joke on difficult customers when we worked in the shop.
A: It is relatively easy to remove the cowl and gain access to the wiper transmission and the walnuts. After removing the wiper arms, the cowl can be popped out. The only tricky part is removing the wipers.
And if Febreze doesn’t work on the smell, have a professional detailer do an odor elimination.
A: According to Einstein’s general theory of relativity, the faster that you travel, the more time slows down. Floor it! Oh, and I don’t think the clock indicates impending problems.
