Another Rant

 So, I would like to first tell all of you that I am working out everyday on the Rack. I am sometimes working out three times a day. It certainly doesn't hurt, so it must be helping. Working out on this machine is a pure joy. There are more than 60 excercises you can do on it! I love it. I guess that is why so many people like their's.

 

          Now, for the "rant" part of this posting. Have you noticed the proliferation of cars that have 22 or 24 inch rims on them? We live out in the country, and I am seeing more and more of them. The worst are the front wheel drive(FWD) cars with these huge rims and tires! Why are they the worst? Well, I will tell you, from the point of view of a mechanic.

 

           When you switch to 22 or 24 inch rims, you have just added more rotating mass to your vehicle. With more rotating mass comes added wear and stress. Larger tires and rims can literally add hundreds of pounds to your vehicle. Want to know a little secret? All that added mass will destroy your drivetrain; that includes the transmission, CV joints, and universal joints. Oh, and did I mention that all of that added rotating mass takes farther to stop? Yep, you give up "braking space".  Let's say your car took 120 feet to stop from 60 mph...now, it takes a lot farther to stop! Can you say "rear-end collision"? You might want to learn it...you will certainly be using it!!!

 

              If you want to go to bigger tires and rims, at least check into some four or six piston brakes.  Do it for yourself, and not for me. You might also want to check into an upgrade for your tranny...it could mean the difference between walking home, and driving.  At least think about these things...what if a small child runs out in front of you? Believe me, you will not stop in time. Physics  are against you. Physics win every time. Be smart, the wheel and tire placards on your vehicle are more than a suggestion, they are a good guideline to follow for your vehicle. Oh, one other thing...larger tires and rims can reduce your vehicle's performance. Why? It comes down to weight...more weight translates to less, or slower performance!
