All New Discovery
DISCOVERY 5 - L462
The New Discovery (Discovery 5) differs from the previous L319 or LR4 in two key areas.
THE GOOD - OFFSET
A good step forward for the New Discovery is that the factory offset is reduced from the previous model. With the standard factory 19", the offset has reduced from ET53 to ET39. This reduction does two things; Firstly, the lower offset means the load is closer to the vertical centre of the wheel, which means the load is more evenly distributed. Secondly, for steel wheels, this means clearance can be increased when the wheel is moved more outboard.
THE NOT SO GOOD - CHANGING BRAKES
Fitting the TuffAnt 18s to the Discovery 5 has been a moving target, with different engine configurations in different markets having different calipers both front and rear. The 2017 brought with it the front calipers of the LR4, made by TRW, but had a different rear caliper. In 2018(depending on production date) the North American market saw the use of the Brembo calipers found on the RRS, with yet again a different rear caliper. Sticking to the norm the 2019 and 2020 seem to follow suit with a change yet again. But this time sticking with the Brembo front, and on some models returning to a slightly smaller rear.
We could only wish it was as simple as X year fits or not, but what we have found is there are many brake combinations being used on the same platform world wide. Some time digging through the parts breakdown will show that it could be determined by year, market, engine, and even original supplied wheel size. All that being said, you must first look at your vehicle calipers before purchasing and if you have any questions please send us an email. Try to include clear photos of your calipers.
To check for wheel fitment, please check the stamping on the calipers. If your front caliper is the larger Brembo and looks like picture #1, the wheels will not fit. If you see a caliper similar to picture #2, you next need to look at your rears. On the the rear break calipers, you should be able to clearly see the marking 4999/C (Left side) and 5000/C (Right side) as shown below.
TUFFANT MKII 18's
In addition to the new design, we have made improvements in the manufacturing process to reduce run-out and to make balancing a little easier. All part of the TuffAnt philosophy of providing the best possible product we can bring to market.
When fitted correctly, the TuffAnt MKII 18's are designed to ensure they are legal in all states of Australia.
As with the Original TuffAnt 18's, the MKII wheels are fabricated from high strength steel, which is then machine pressed, machine welded plus painted then powdercoated in black to provide a wheel that is rated at 1000kg each.
Note: All Discovery 5's delivered in Australia only have tyre placards for 19" rims and above. (Discovery 4 is 17" and above) It is TuffAnts understanding that as long as the overall diameter of the wheel and tyre combination is within state regulations, as well as the offset is not exceed by more than 25mm overall (varies in different states), you may need to check with your motor vehicle insurance company to ensure there are no issues with your motor vehicle insurance policy.
Whilst TuffAnt sells these rims as compliant in all states of Australia, it takes no responsibility for individual warranty or insurance issues for their use.
