165HR400 Steel belted radial with correct diameter and awesome handling and ride characteristics. These are the best 165R400 tyres ever made, and you will not believe the improvement in handling these period correct Blockleys will result in. A size used for many Lancias (Aurellia , Flaminia ,  Aprillia) , Alfa Romeo 1900 , Ferrari and even Citroen Traction Avant, the 165R400 size being the first radial tyre size available to the public.

This Blockley 165 HR 400 is a modern designed full diameter steel belted Radial tyre, with a good speed rating (H speed rated - 130mph / 210kph) with period correct tread pattern, designed in house. The 165R400 tyre is a radial replacement for the cross ply tyre sizes 130x40 and 140x40. These Blockley 165HR400 tyres are E Marked as well as DOT marked for use in the USA.

Please note that Pirelli (a brand owned by the Chinese government) claim that their Cinturato "CA67" 165HR400 is the only H speed rated 165R400 tyre, but this is not a correct statement. The Blockley 165R400 tyre is H (130mph) speed rated, abut the big difference with teh Blockley is that it has the correct taller larger diameter!

Blockley produced this 165HR400 tyre so there could be a proper speed rated and infinitely better handling tyre than the Michelin which was the only 400mm wheel size option, because something much more wholesome has been needed for some decades. Knowing the Lancia Aurellia and Flaminia Zagato pushed me to commit to this unusual millimetric size, which required much in the way of specialist tooling. Since starting this project Pirelli also have produced this size with the same speed rating as us, but the Pirelli diameter is too small! These 165R400 Blockleys will be the best you have ever driven on and come with the usual Blockley radial tyre guarantee to scrub them in and if you are not overjoyed in every aspect over the next 1000 miles or so we will offer a full refund. Anyone previously using a 165R400 tyre size is in for a nice surprise!

The 165R400 is also a good tyre size for a Traction Avant Citroen over the cross ply 130/140x40 and 150/160x40 cross ply tyre sizes available now, the Blockley being a great handling tyre and very cost effective alternative choice. The 160/40 tyre was listed with Citroen from 1932 and the 165/400 size was listed with Citroen from 1939, and used on theTraction Avant until production ended in 1957.

Please note that as per original period specification this 165HR400 tyre is a tube type, just as the 165R400 size was in period, so you will need to fit a correct fitting inner tube - see below.
