For Barry or others. I asked my friend if he specific questions and he came up with these.
(1)Are "factory" wheels, generally speaking, stronger, more capable, than they have to be, need to be, to meet the minimum standards the automaker, needs, for that vehicle? Same question for tires?
(2)You see remanufactured, cosmetically restored, wheels, for sale on ebay, everywhere. How safe, or unsafe, can these be? Are there any standards, for what can be brought back to life, vs not saveable? How do you know, what was done, to cosmetically, restore a wheel?
Everybody, wants bigger wider wheels, with lower profile tires. However, I'd like to switch my Lexus GS wheels, from 16x7.5 to 16x6 to save weight, and allow that same wheel/tire combo, to be used on either my 1999/2000 Toyota Avalons, or my Lexus GS cars (1998-2000 ).
(3) For my Lexus GS cars, what will I "give up", when I go to a narrower, lighter wheel, from a heavier wider wheel, and yet continue to use the exact same tires? I'm switching from 16x7.5 Aluminum ( stock on Lexus GS 1998-2005 ) to 16x6, Aluminum ( optional/stock on a 2000 Avalon ) ,,, both wheels, are ET45, 5x114.3, both are stock, Lexus/Toyota Wheels, from the 2000 model year... The tires stay the same, at 215/60/16(V).
(4) generally speaking are factory wheels simply a commodity, or do certain car manufacturers, pay more, to have better wheels made?
(5) Same question for tires...
(6) Are higher speed rated tires, going to hold up longer, and be safe longer, than lower speed rated tires, if all other variables are equal?....... in regards to tires that dont get a lot of use, and still have lots of tred remaining, but are now older than 7 years, old?
(7) Tires older, than 7 years old, that sat down in a spare tire well, under the trunk floor, but look absolutely brand new, feel brand new, etc, and have never been on the ground... Generally speaking, are they still safe to use, now, being 8-20 years old ?
