Perhaps a thorough inspection of the suspension is in order to ensure coils and absorbers are in good order. Bushings and mounts could also be a culprit. Tyres nearing their end of life can be a huge contributor to ride quality.

Fwiw, kumho is generally a very hard tyre hence the high treadwear ratings when compared to other brands. I won't be surprised if the tyre hardness is what's contributing to the ride quality. Harder tyres tend to offer less cushioning hence you feel the road a lot more especially on bumpy roads but offer a longer life. Softer tyres provide better ride quality but wear faster.

If you want to have an lpidea of how hard a tyre is going to ride, press your thumb into the sidewall of an unmounted tyre. The more resistance the harder the ride.
Performance tyres, run flat tires, lower profile tyres, higher load capacity tyres tend to have stiffer sidewalls which usually means lower ride quality.
I would like to think age hardened tyres affect ride quality negatively but I don't let ride comfort affect my decisions much
If you want to look for indicators on the sidewall of the tyre.
Lower load index/lower load capacity = generally better ride quality
P-metric has a slightly lower load capacity than its metric equivalent which means it rides slightly better (that P in "P225/65r17")
Look at the number of plies in the sidewall, less generally means more comfortable; this is directly related to load capacity. Avoid LT if you want comfort.
Taller tyres (more rubber between the rim and the road) generally equates to more comfort.
Less unsprung weight lighter or smaller rim generally gives more comfort.
Lower air pressures (within reason) can make the ride slightly more comfortablecarluva wrote:Goodyear Wrangler SUV.

carluva wrote:Well you are correct. Treadwear is actually a measure of wear resistance of the tyre. However a high treadwear rating usually means a hard tyre. Hard tyre means less cushioning and hence a harder ride. That's why kumho tyres are generally regarded as harder tyres than many others and further associated with "rougher" ride. On the flip side, tyres such as Toyo generally are associated with smoother rides but wear very fast.
Low profile tyres also offer less rubber between the road and rim. Same for ride quality.
While a taller tyre offers more rubber, again, treadwear is important a tall tyre with high treadwear will ride harder that a tall tyre with lower treadwear. That is why the same size tyre from different manufacturers but with different treadwear ratings will feel different.
Personally, I always tend to choose tyres whose treadwear iis < 400, ideally around 340-360.But that's for car or SUV. The tyres on our RAV4 are 340.
For 4x4 equipped vehicles or "large SUV", a good AT tyre will usually be >400 treadwear. The tyres on our Fortuner, while not AT are 440. However these are highway tyres (i.e. 80% road, 20% off road), so the ride quality is very good compared to the AT tyres.
However, for the Fortuner, the stock suspension is excellent so even with these harder tyres the road is not felt as much as when I had AT tyres on it. Road noise is also reduced.kamakazi wrote:I was unaware that Treadwear is an indicator of tyre ride quality. Treadwear cannot be used to compare tyres from different makes

I brought in some 440 wear tyres for the wife's car for that same reason and while many year ago manufacturers started pushing the use of certain compounds that both offer comfort and longevity I am still wary of those guys over 500 wear guys.

But, would what you've quoted there apply as the RAV4 is a CVT and not your normal geared transmission?
