I see that the RAV 4 now comes with a model without the tire on the back. Which off hand I like better. However, I wonder about having only 4 tires and them "run flat tires". Questioning how those "run flat tires" ride as compared the regular tires.
It seems that you can go 50 miles on them after picking up a nail et al which is fine with me since I won't be driving anywhere that I cannot get it repaired more than 50 miles away.

From what I understand the ride is going to be stiffer from the thicker sidewalls on the tire, and the 18 in wheels vs the 17" on the other models. Also f you are leasing, how much will it be to replace those tires when you return it?

Run Flats on vehicles that didn't come with RunFlats?
1) The ride on RunFlats is considerably harsher.
2) In addition to the tire needing redesign to be capable of running flat, the rim has to be stronger (meaning thicker and heavier)
3) The rim has to have what is known as an EH2 or EH2+ safety hump so the bead of the tire stays on the rim. Otherwise, the tire will debead itself and the rim will be ruined.
4) The TPMS system is required so you know the tire has lost air. RunFlats don't feel much different when running flat.
5) Repairing RunFlat tires is hotly debated. If you look past all the verbage, The problem is that when a normal tire is run flat, the sidewall gets damaged. This damage occurs with RunFlats, too, but much slower - which is why they say 50 miles is the limit for running flat.
When repairing a normal tire, you can see this damage - sometimes on the outside, sometimes on the inside. On RunFlats, the damage is under the stiff rubber insert and you can NOT see the damage even if it is there! Clearly after 50 miles, there will be damage. If a RunFlat tire is damaged in the sidewall and then repaired, it could fail - just like a normal tire - and if that failure occurs at high speed, the vehicle could go out of control - and that's always bad. The failure will be sudden - just like a normal tire - and the RunFlat capablility will not be there.
Overall, not a good reason to make the attempt.

The original post was in reference to the factory Rav4 Sport with the Appearance package which comes with run-flat tires and no spare tire, which personally looks great w/o that spare tire hanging on the back of the Rav.
I'm quite certain that you can install a conventional tire on the rims when it comes time to replace tires.

Replace the "Run Flat Tires" with "Conventional Tires"? What would you do for a spare tire? And I do understand they do ride rough comparatively speaking which may be good for younger people but not for this old gal.

Carry a can of tire sealant? How often does one get a flat tire?
Many new cars are doing away with spare tires and come with a can of sealant.
A guy I work with that has a BMW, says many a BMW owner changes to conventional tires and has roadside assistance coverage in case they have a flat.
I personally think Toyota could design to do away witht the exterior mounting and have a space-saver spare inside. Maybe for 2012? They don't need to continue with the exterior-mounted spare "because that's the way it has always been".

I much prefer a spare. A can of sealant won't do much good for a blow out or a sidewall tear.
#8 of 24 Any adjustments possible?
Mar 09, 2011 (9:52 pm)
I just purchased an '09 Sport (V6, 4WD), and indeed the ride is pretty rough. I didn't appreciate it until I drove it on rougher, pot-holed roads.
In any case, I generally like a stiffer ride and better handling, but a little softer would be nicer. Does anyone know any adjustments that can be made (without compromising safety, of course). For example, can a slightly lower air pressure in the tires be used? Will that damage the tires over time? Affect gas mileage a lot? Can any adjustments be made to the struts?
Thanks for any experience and advice!

Since the Sport model comes with not only run flat tires but also stiffer sport suspension, your options for softening the ride are limited to replacing the run flats with conventional tires and/or the sport shocks with the standard shocks for any non-sport RAV.
Either or both are quite doable. If you opt for non-r/f tires - get a can of tire sealant and a 12v compressor in case of a flat.
If you ever do sustain a blow-out or sidewall damage, just call for roadside assistance to get the damaged tire/wheel or whole car to a tire shop.
Very doable if you cary your cell phone and AAA card.
Do not drive with tire pressure lower on run flat tires. This will not improve the ride at all as the sidewalls have no flex, hence no cushion.

Anyone replace their run-flats with conventional tires for the RAV4 Sport? I have a 2010 with rf's and will probably replace the tires next year, mostly to improve the ride quality. Thanks.
