Yes, decreasing the thickness of your tires affects ride quality. It depends on how much of a change you are making and on the tires themselves, but in general, if you install larger rims with thinner tires, you will feel the roughness of the road more and small bumps will feel like they are hitting harder.
If by 'thickness' you mean the distance out from the wheel rim to the tire tread, a better term is the tire's 'profile'.
Tire sizes are indicated by numbers for width/profile ratio and rim size. For example a 205/65 16 tire is 205mm wide with a profile that is 65% of the width or 133.25mm (205 x .65) on a 16" rim.
Most auto tires today are radial design which would be indicated by a "R" prefix i.e R205/65 16.
Generally, tires with lower profiles do ride 'harder'.
They will also last longer due to having less flex in the tire wall and improved gas mileage due to less road 'drag' or friction.
But less friction also means less braking action and traction - it will increase the distance needed to stop the vehicle and are more prone to slip on the pavement with extreme acceleration.
If you can have good winter tires fitted to them, there's nothing bad with having 20" tires in snow.
Poor or rotten roads make rough riding while thin layered tires add more to it as well.
The 22 rims will ride okay although you are putting an extra extra strain on your transmission not to mention u cant travel fast on interstates and highways due to the friction to slow your car, and the rims down in case of emergency. I would suggest getting some 20's and adding rubber band tires to those to give it a bigger appeal.
245/35/18 tires, this is a bad idea it will cause massive suspension problems and will warp the rotors
Perhaps bad tires or bent rims bad axle shaft? swap front tires for rear to see if problem persists
Make sure the size of the rim is appropriate for the make and model of your vehicle. A bad fit will affect ride and mileage, not to mention tire wear. Your tires should be matched to the area of the country you are living in. Do not over pay just for the brand name.
23" rims would not only look bad but the wheel wells on a 1993 Camry are too small to support a rim that large once you add tires.
The wheel balance was not done properly, or there may be a bad tire.
No, this is a very bad swap. Your speedometer will read 57.8 at a true 60 mph. This swap will adversely effect handling, ride, and performance.
you can fit 315'75r16 on there, i believe it is an 8 lug, they will more then likely fit on your stock rims even, the front will rub a little but it really isn't bad, don't get mud tires if your only mudding on the weekends or just every year, it is never a good choice, thoes are 33'' tires, and 12.5 inches wide they fit
Bad tires and bad alignment can cause the car to shake at certain speeds.
