Tyres for the Prado Last Updated: 02 September 2010 The Landcruiser Prado normally uses the 265/65/17 sized tyres. Initially a niche choice there are now lots of manufacturers to produce tyres in this size. The tyre brand and model commonly used by Toyota are the Dunlop AT20 or A/T 20 as OEM tyres. If you search on the web you'll probably find that these are not the best tyres available. But more often you will find out yourself. However the Dunlop AT20 are not all bad, their sole redeeming quality is that they are quiet road biased tyres. The Dunlop AT20 can last up 50,000 km if you treat them well. The AT20's didn't last very long for most of us and replaced at about 30,000-40,000km. Here's our story on what we replaced them with. |

There are a few common choices as replacement tyres for the At20. The Bridgestone D694 is the most promoted tyre as a good replacement. Hard to find in 2007 but much easier in 2010. In fact I initially waited 4 weeks in the hope that they would be available but in the end still weren't. So I looked for another model. So I didn't want to get a different size tyre for various reasons so I searched for other brands. BF Goodrich, and Goodyear all had various LandCruiser compatiable models but again size was the problem. In the end I bought the Cooper Discoverer ATR.

Copper ATR on-road experience: We are quite picky about noise, because when the Prado does long distances, quietness is a very important factor in keeping alert and general comfort. The Cooper Discoverer ATR is not a noisy tyre but noisier than the Dunlop AT20 but not by much. I can't really complain. Off-road experience: Initial summary: I initially had wheel alignment problems but solved by increasing the tyre pressures to 40psi. The ride is firmer due to the higher pressures but that's expected. Tyre wear around the edges is absent - which bodes well for tyre life. So if you have wheel alignment problems try adjusting the tyre pressures first. Price The price of Dunlop AT20 vary: I was quoted
between a price range of $200-280. The retailer wasn't chosen wasn't the cheapest but the nicest to us. Issues and summary The Cooper ATR is overall a better tire than the AT20 without any significant downsides. These tryre are suitable for all types of roads despite the off-road style thread. Whether another tyre like the much promoted Bridgestone is better I don't know. Maybe at the next tyre change. After 10,000kms the tyres are holding up well. I've noticed very little wear. The extra road noise is not noticed around town and on freeways its still more than acceptable. UPDATE: 12 months after purchase the Discoverers ATR Still had plenty of thread left. Wish I kept track of how many kilometers they have covered! The tyres where rotated recently and I could tell that the newer ones where in the front. The initial tram lining returned and sensitivity to road imperfections where again immediately noticeable. It should disappear after the next interstate trip. UPDATE: After 40,000km there is still plenty of tread left so I anticipate at least 60,000km before I even nee to consider replacements. I have also found the sweet spot for me - at least in terms of the optimum tyre pressures. 42psi if you really want to know! The ride is firmer and the alignment, wear and handling is just to my liking. Considering the now worn in suspension it seems to balance it out? Well at least I think so. I think I will replace the tyres at 50,000km on the basis that a change is as good as a holiday and its something else to write about! UPDATE: Didn't replace them - tyres are expensive. After 70,000km
still have lots thread - think they might last over 80,000kms.
Others are on 2nd set but still no reason to change to another tyre... |
