To simplify the critical factors to check for your chosen skinny wheel are: CHECK 1 (OBVIOUSLY) Will it fit on the studs? Does the skinny wheel have the 'standard' LEXUS/TOYOTA stud pattern (PCD) of 5 x 114.3? If not, move on! CHECK 2 Is the outer diameter / rotations per mile within +/- 3% (2.5%) of the original? Why? It reduces, as I understand, potential transmission system stress to a minimum. Use a tyre size comparator tool such as found at: https://tiresize.com/tyre-size-calculator/ E.g. My original tyre size 235/45R18 One suitable skinny tyre size would be 135/90R17 Difference in rotations/mile 1.1% Not suitable would be a skinny wheel I was offered (from an NX300h) NX300h skinny tyre size 165/80/R17 Why? Difference in rotations/mile 4.2% My motto is: 'Don't overthink it: Deep thinking can be positively dangerous especially for those who don't'

Many people have raised issues about size equivalence of skinny wheels. My understanding is the offset of the original wheel shouldn't matter [see below] as the spacesavers are 'skinny'. So nothing is going to get 'stuck in the works' anywhere. I'll give you an example. LEXUS/TOYOTA WHEELS ARE 5 stud with a PCD Bolt pattern/PITCH CENTRE DIAMETERS) [diameter (mm) of an imaginary circle through the centre of the studs/bolt holes] of 114.3 mm. 5x114.3 with a centre bore of 60.1mm (diameter of the hub [hole in the middle of the wheel]). Also various wheels have different offsets. (The difference in mm between the tyre centreline (half of the width) and the hub to the top of the wheel in mm). This figure can be positive, neutral or negative. So, My 2023 LEXUS ES300h PE has 235/45R18 tyres. A suitable skinny wheel might have a size of 135/90R17 tyres. Here the skinny wheel diameter is small but the tyre depth is more which compensates. The important thing is that the difference in outer diameter of the tyres should be no more than +/- 3% or less. With the above example you can do the comparison the long way using tyre sizes and tyre size definitions and some trigonometry OR cheat and use a tyre size comparator tool such as: https://tiresize.com/tyre-size-calculator/ There is a seller on eBay who sells good condition OEM Toyota/Lexus skinny wheels sparewheelsdirect (5235) for about £100. Unfortunately they do not give the skinny wheel sizes so that you can use a comparison tool to check for yourself. For about £150 thewheelshop.co.uk supplies new skinnies. If you tell them you vehicle and tyre size details they will

Steve, I agree that Lexus parts direct https://lexuspartsdirect.co.uk/ are very good, but for this part I was quoted £400+. Sometimes also Then because the lady started from my reg/VIN I was not convinced that I was not going to get the UK supplied tray which fits the whole wheel well as the short part numbers are identical. Another alternative UK supplier is https://www.oemlux.co.uk/ they quoted around £300 for the tray My local dealer reluctantly confirmed the long part number (as quoted on this forum) but the parts guy quickly said it's not for a UK supplied vehicle so no warranty/no returns! Great service for £400 I thought. Especially for a non-critical part. I couldn't resist sarcastically replying if you fit your own rubber boot tray/liner I suppose that voids the warranty! With regards to HMRC we will see if I am contacted by the FEDEX handling agent for tax on an amount paid of £100.98!

My dealer and a number of UK OL Lexus parts suppliers quoted a price of just short of £400 for this piece of polystyrene! I looked at the following overseas suppliers who have a good reputation with goods coming from Toyota Central Spares locations and got one for a little over £100. These sites are: https://yoshiparts.com https://www.amayama.com/en https://www.megazip.net https://partsouq.com They all have good software with on screen access to the parts catalogue pages with short and full stock numbers. So, for example, for the space saver tool tray the short number (PCN?) is 64779E for the UK supplied deep one (on the left) and the one that covers a space saver in the middle of this picture. But when you click on the latter you get its full part number 64779-33280. Now, I don't have to be 'nice' to the dealer's parts guy and find him/her on a good day (an oxymoron I think)!
