Rich_P Posted February 17, 2009 Share Posted February 17, 2009 Hi again. I'm trying to figure out the closest Metric equivelant to the 7.00 R16 tyre size. I've come up with it being somewhere between 205/80 and 215/85. Anyone know of what may be a common size that's very close if not the same size to 7.00 R16?

Pete Attryde Posted February 18, 2009 Share Posted February 18, 2009 I suspect the closest size would be 235/70/16 which is a standard size for discovery 1's, has a diameter of 29" HTH Pete. Quote Link to comment Share on other sites More sharing options...
Rich_P Posted February 18, 2009 Author Share Posted February 18, 2009 That has the same height as 205/80R16. 7.00 tyres have a height of 177.8mm and 205/80R16 has a height of 164mm. 235/70 has a height of 164.5mm... Quote Link to comment Share on other sites More sharing options...
Pete Attryde Posted February 18, 2009 Share Posted February 18, 2009 another option would be 245/75/16 which has a diameter of 30.5". Pete. Quote Link to comment Share on other sites More sharing options...
cipx2 Posted February 18, 2009 Share Posted February 18, 2009 Hold on gents, you're going the wrong way.... A 7.00R16 tyre has the following characteristics: - radial construction - rim width code: 5.50 - nominal rim diameter: 406 mm - outer diameter: 784 mm (30.86 inches) - section width: 198 mm From the above, you can determine the aspect ratio: ~95% The closest aspect ratio on metric tyres is 85%, so you can start from that. Use your favorite tyre calculator and see what you can come up with. THIS seems to be the favorite tyre calculator on this forum. The nearest metric equivalent seems to be 225/85R16 (0.6% larger outer diameter). Or you can go on LR's hand and choose what they use instead of the skinny 7.00R16 on Defenders: 235/85R16. The issue is that either 225 or 235/85R16 require a wider rim than the 5.50 used on 7.00R16 tyres. As you see, theoretically speaking, given the rim width and the aspect ratio,.there's no metric equivalent for a 7.00R16 tyre. In other words, there's no metric tyre with the same overall diameter as skinny (narrow and tall) as the 7.00R16 and that fits the same rim as 7.00R16 does.

Mark Posted February 18, 2009 Share Posted February 18, 2009 Why do you want a 7.00R16? It seems a funny size. Std LR is 7.50x16 for LWB vehicles and 6.00x16 for SWB vehicles (series and defender). The metric replacements for LR's were 235/85-16 and 205-16 respectively... Mark Quote Link to comment Share on other sites More sharing options...
BogMonster Posted February 18, 2009 Share Posted February 18, 2009 What CIPX said, followed by the question why would you really want one? It's an odd size and the only LR I can think of that they were ever used on in recent years was Camel Discoverys and the later ones of those went to 225/75R16 I think. I believe the Michelin XZLs are available as a 7.00R16, they certainly used to be anyway. Quote Link to comment Share on other sites More sharing options...
Rich_P Posted February 18, 2009 Author Share Posted February 18, 2009 Thanks chaps. The question was for someone who I know who was interested in getting as close to the 7.00 tyre size (like what the CT motors used) as possible, given that they appear to be the tallest tyres that you can use without having to mess about with suspension alterations. Said chap wasn't wanting a super wide tyre either, so I guess 205/80R16 might be the best size given its width and height? Quote Link to comment Share on other sites More sharing options...
BogMonster Posted February 18, 2009 Share Posted February 18, 2009 Why not just get 7.00s then - I think they are still available in the Michelin XZL (not sure about the Mich XCL, which was what a lot of Camels used, I think they stopped making those) Quote Link to comment Share on other sites More sharing options...
Steve H Posted February 19, 2009 Share Posted February 19, 2009 Sorry to say Gents, you're all wrong. From owning a 88" SIIa which originally came with 700x16s SATs on, OK 3 SATs & a Triple Traction, I can say for sure that the nearest radial that will fit on a std series rim (5.5" LWB admittedly) is a 215/85 R16, all but the same diameter as the 245/75 that Pete posted but they need at least a 6.5" wide rim. I ran some Hankook RT01s in this size, they were excellent & kept the speedo correct as well. This link will show what I'm on about.
